WebJan 5, 2024 · The collapse capacity of high-rise SMRFs with thin-walled FB members (20S-FB c-FB b, where the subscripts c and b indicate column and beam components) is assessed based on the incremental dynamic analysis (IDA) method by excessively scaling the intensity of input ground motions. The IDA approach was proposed on the basis of the analogy … WebSep 30, 2024 · Finite Element Analysis often advises that thin-walled parts should only be meshed using solid elements if it is possible to use at least three elements through the thickness. Otherwise, use shell elements. This advice, however, assumes the use of first-order elements, which are rarely used in modern FEA software.
