COURSE OBJECTIVES

The primary objective of this course is to provide architectural students with the essential skills to perform structural analysis of buildings. Students satisfying the course requirements will be able to:

1.        Analyze forces and determine reactions.

2.        Calculate forces generated in elements of a structure.

3.        Locate critical points in a structure for internal loads and stresses.

4.        Locate and determine center of gravity and moment of inertia.

5.        Develop shear and moment diagrams.

6.        Calculate strain in structural members.

7.        Analyze and design columns.

8.        Analyze and design steel connections.

9.        Choose appropriate structural materials and framing system.

10.     Understand the relationship between loads, force, stress and strains.

11.     Follow the load path through a structural frame and determine whether the frame is stable.

 

This course develops an understanding about the concept of force equilibrium. Force equilibrium represents one of the most basic yet powerful concepts in the field of structures for architects, and is the basis for the understanding of structural behavior. At the completion of this course, the student should have a sound understanding of this concept and be able to utilize it in analyzing statically determinate force systems. Emphasis is on force analysis involving external load conditions on a structural system. A primary objective of part two of the section in strength of materials is to develop a working relationship between applied loads on a non-rigid body and the resulting internal forces and deformations induced in the body. Strength of materials is concerned with the properties of various structural materials (wood, steel, and concrete) in resisting applied forces. Upon completion of this section students should be able to evaluate the appropriate interplay of stresses, section properties, material strength, and deformation based on an analysis of the load and support conditions present on a structural member.

 

COURSE DESCRIPTION

This course is a lecture class that focuses on structural analysis for architects. Students will learn to efficiently organize, coordinate and communicate information in order to convey data necessary for structural analysis.  Incorporated is an applied research project and field sketches related to structural design and detailing.

 

Students will gain exposure to the essence of structural design.   The following subject content will be addressed. Loading determination and evaluation.  Resolution and equilibrium of force systems. Truss analysis.  Centroids, moment of inertia, and shear and bending moment diagrams.  Basic beam, column and system design.

 

ATTENDANCE POLICY

Students are expected to attend class regularly and punctually.  An attendance sheet will be passed at each class meeting.   All students must attend all scheduled field trips.  Absences will be excused only by 1) family emergency, 2) documented medical stay, or 3) approved college function. Note: there will be a full grade deducted from your final course grade if more than three unexcused absences occur. If you are late to class it will be your responsibility to sign the class roll and pick up assignment sheets.  Three "lates" to class will equate to one absence.  In the event that a student misses a class, the student is responsible for all material covered in the class. (See www or classmates for handouts). 

 

GRADING POLICY

a.     Purpose: To measure and record your comprehension of the issues presented by the professor or the project; to measure and record the student's progress in mastering the manual and intellectual skills necessary for the practice of structural analysis; to measure and record the effectiveness of the teaching method (course or project calculations and its administration); to inform you about your strengths, weaknesses, and progress.

b.     You are evaluated on your comprehension of the subject matter taught in this class.

c.     Grades will be available to you upon request in a reasonable time following each exercise and/or exam.  Grades will not be posted.  It is your responsibility to request information on your grade assessment from the professor.

d.      Mid-term and final grades will be in accordance with Temple University's policy and timetable.

e.     An interim review will be conducted with each student dropping below a “C” average with the dual purpose of undertaking a student and faculty evaluation.  The professor will meet privately with you following the issuance of mid-term grades to discuss your progress and to provide an assessment of your performance to date, what is expected of you for the remainder of the term, and to provide you with an opportunity to assess your own development in the course.  You are encouraged to request conferences with the faculty to discuss your progress at anytime during the course of study.

ASSIGNMENTS

1.        Students are to prepare weekly homework as stated in the course outline. Homework problems are assigned for each class meeting. 8 or more homework submittals will be arbitrary collected for grading on the due date as quizzes. All work is to be handed in at the time designated. All homework is to be handed in on the next class meeting following the assignment.  Late homework collected for grades will NOT be accepted and you will receive an "F". The lowest homework/quiz grade will be dropped. A missed homework is automatically the one that is dropped.  Homework collected as a grade is due by the beginning of class.  Do not email homework to the professor. The homework assignments will be submitted in the form of professional architectural engineering documents on grid paper.  Homework must be worked showing all calculations in writing (pencil).  Homework must strictly follow the homework format provided. The required computer software will enhance your ability to understand the material and check your work for the correct answers.  The use of the software is beyond the scope of this course and will not be taught in the class.  Download the software and utilize it throughout the course where possible.      

2.        Work that is not neat and clearly legible will be marked down and is subject to not being accepted.  Neatness implies accuracy.

3.        All homework, quizzes, test and/or exams are open book.

4.        Two comprehensive tests will be given.  The first test will cover statics and the second test will cover strength of materials. The material on both exams will be taken from the required text and lectures. 

5.        The research project will be to provide a structural appraisal report on a historical building. Your submission should be generously supported by annotated sketches and calculations. It should be 3000 words in length, excluding appendices. As architects you should be taking a leading role in sustainable design, green architecture and building conservation.  We often see beauty in abandon structures that others see as eyesores. In summary, the scope of services includes the following. 1) Visually inspect the existing building noting damage, deficiencies and overall condition. 2) Perform analysis of the existing structural system to determine code compliance.  3) Identify repairs required to the existing building. 4) Perform analysis of the building for varying stages of conservation including associated cost estimates.  5) Investigate compliance with ADA guidelines involving structure.  6) Determine a new use for the building.  Your report should clearly explain the structural system of the building, i.e. the way loads and forces are distributed through the building to the ground. Using the dimensions and likely weights of the materials being supported, estimate the stress level in one element in each of the following categories: 1) A wall, whether solid and loadbearing or framed with infill. 2) A floor, including joists, boards, any ancillary materials. 3) A structural component in the roof, such as a joint, rafter or purlin. 4) The foundations at one point where loads reach the ground. Compare the stress level with the likely loadbearing ability of the element concerned and comment on the occurrence of any visible deflection, deformation, cracking or settlement, which might confirm the successful operation (or otherwise) of the structural system in use. This assignment is primarily about identifying how the building works as a structure. The research project is to include field sketches representing elevations, sections, important structural details, connections, roof framing, ceiling framing, floor framing and foundation layout.  Both transverse and longitudinal sections through the structure should be sketched, etc.  All sketches should be clearly documented to show all necessary load paths and how loads are transfer from point to point.  Your report should include all structural items that concern you as an architect and suggestions for repair.  You are encouraged to follow both the intuitive and mathematical paths in your analysis. You will need to make several trips to the site to document and study the structure.  Visit the library, city or county building permitting office, etc.  to obtain the history of the structure and other related information as required.  Obtain advice from consultants when required (students in landscape architecture, construction engineering technology, engineering, architecture, etc.).  Fieldwork can be dangerous; do not take unnecessary chances when documenting the structure.  Keep safety in mind at all times and always work in pairs.  Use digital cameras, levels, transits, lasers, etc. as required.  Use structural terminology that you learn in class when discussing the project and be prepared to explain that terminology.  This is a real-life project, take it seriously and conduct yourself as an architect when visiting or discussing the project. Be aware of the difference between analysis and design.

6.        Late submission of the final project will result in the reduction of a full letter grade or failure of the course.

 

MATERIALS AND EQUIPMENT

1.   Standard drafting equipment as used in previous courses (scale, protractor, etc.).

2.   Engineering Paper (green with grid lines) is to be used for homework and quizzes.

GENERAL POLICY

1.        The class is to be handled and conducted in a professional manner.  Student attitude and participation are required if the class is to be passed successfully.

2.        Provide your email address to the professor by emailing jmkelly@temple.edu

3.        Students are required to check the web announcement page and their email daily. Posting on the announcement page or email constitutes official notification.

4.        Selected solutions may be posted on the web page if time permits.

5.        Please disable cell phones in class.

6.        Do not procrastinate in doing the homework problems by starting the day or even several days before the due date. Start the assignments early and complete all problems before the DUE DATE. Successful completion of the homework and test are a major percentage of your grade.  I cannot stress this enough because if you do not work the problems successfully and do not hand them on due dates you will FAIL this course.  The structural portions of the ARE Architectural Registration Exam are very difficult. Most of the material presented in this class will not be taught in an architectural office.  A building must have a good and solid foundation capable of supporting the loads for the life of the structure or the structure will fail. This is your foundation course in structures, study hard and learn it well.  Pier Luigi Nervi said, “In order to invent a structure and give it exact proportions, one must follow both the intuitive and mathematical paths”.  The main emphasis in this course will be on the mastery of basic principles, which will lead to successful solutions to real-life applied structural problems.
