Integrated Analysis and Design of Steel Frames with Interactive Computer Graphics

摘要

An approach is presented for the interactive computer-aided limit-state design of statically loaded steel rigid frames. Two strength procedures implemented for treating ultimate limit states are discussed. One is based on elastic analysis with code-type design equations used to evaluate the response of individual members. The second is based on full nonlinear analysis, which considers both geometric and material nonlinearities. The nonlinear analysis techniques are tested and their suitability for the design process is demonstrated. An example of the design of a three-dimensional structure is presented. The designs obtained using first- and second order elastic analyses are verified by studying the behavior of the structure as the loads are increased from zero-load state to collapse.
