Knowing the percent of surcharge, one can easily d~termine the actual equivalent fluid
weight (Yeq) following the methodology given in Sec~ion 6.2.

11.4.3 Wall Support Conditions

An important factor in basement design is the wal,1 support condition that exists. Wall sup-
port condition refers to the kind of reactions that ~alance the force 'imposed on the wall. The
kind of wall support at the top and bottom of the f-vall will determine the location and
magnitude of the maximum bending moment that pccurs due to a given loading condition.
The maximum bending moment, in turn, governs t~e actual structural design. The three sup-
port conditions that might be assumed are shown In Figure 11.1 and given below:

1. The wall is simply supported, that is, no mom"nt at either end.

2. The bottom of the wall is a fixed end while the top is simply supported.

3. The bottom of the wall is a fixed end and the' top is a free end with no support. Such a
support condition is called a cantilever.
