Abstract

Construction in civil work has found many problems. One of them is the imperfection of
the structure which is inevitable. This will affect behavior of structure both nonlinear geometric and
nonlinear material and will make structure unstable leading to decreasing in the capacity of structure.
This research presents a simulation of loading behavior of space truss using both nonlinear geometric
analysis and nonlinear material analysis. In addition, the imperfection in cases out-of-straightness and
out-of-plumbness were considered. The analysis result showed that the capacity of some type of space
truss are very sensitive to the initial imperfection. As a result, the structure will deform to its unstable
condition more rapidly.
