GENERAL COURSE DESCRIPTION (UM SCHEDULE OF
CLASSES, FALL 2002): Structural design of members for buildings and
bridges subjected to tensions, compression, shear and bending. Materials:
structural steel and reinforced concrete. Design of welded and bolted
connections. Placement of reinforcing bars in concrete members.
HOMEWORK ASSIGNMENTS:
Professional presentation of homework assignments is
required. Professional presentation consists of neat and organized
solution of problems on one side of 8.5"΄11"
papers. Any homework not complying with professional standards
will not be graded and will be assigned zero credit. The homework
assignments are due one week after they are assigned. Homework will be
assigned as the material is covered and will be collected every Monday at
the beginning of the lecture period, starting on Monday 9/9. Assignments
turned in late will be docked 10% for each day it is late past the
original due date. Solutions will be available from the TA and on the
class website after the problems are returned. No assignment will be
accepted after the answers have been posted. Students are encouraged
to discuss and formulate solutions to the problems by working in teams.
However, assignments must be completed and submitted individually.
Simply copying the answers from another student or from a solutions manual
is not acceptable and will not be tolerated. Guidelines for homework
are given below:
1.
Use good quality paper, such as engineering graph
paper or college-ruled paper, any color, with no spiral edges
2.
Write on only one side of the paper
3.
Either pen or pencil is acceptable
4.
Include your name, section, and page number (e.g.
1/3 means 1 of 3) on each sheet
5.
Staple all pages together in the upper left corner
6.
Neatly box all answers, and include appropriate
units for numerical answers
7.
Show all work (e.g. no work means no credit
will be given)
If the above guidelines are not followed, the TA will
either reject the assignment outright, for extreme cases, or deduct points
for items that do not conform to the specifications.
EXAMS AND QUIZZES:
All students must take all exams and quizzes
including the final exam. Only extenuating circumstances will be accepted
as an excuse for missing an exam. The student must notify the instructor
of the reason for absence as soon as possible. Health related excuses
require medical reports and the signature of a
physician that provided treatment. You are encouraged to go over
Chapter 4 of the Undergraduate Catalogue for the University policies, or
visit http://www.inform.umd.edu/ugradcat/chapter4/attendance.html
COURSE WEBSITE: Students are encourage to
access course web site at http://www.ajconline.umd.edu to download course
materials such as homework sets and solutions. Timely information will
also be posted on the web site. At initial login, use your wam account
name as the username, and your SID as the password. You are advised to
change your password after your first login. Report any problem with the
course web site to the instructor. For technical problems of the web site,
