FEM/I: A Finite Element Computer Program for the Nonlinear Static Analysis of Reinforced Masonry Building Components (Revised)

摘要

The report describes a finite element computer program or code, FEM/I, that has been developed for the nonlinear static analysis of reinforced masonry building components subjected to in-plane loading. The computer code will be used to provide element properties for the structural component models (SCMs) being developed and for the lumped parameter models (LPMs) being developed. These element properties are most reliably obtained from experiments; however, it is not advisable or economically feasible to conduct a sufficient number of tests to provide data for every possible modeling need (i.e., component size, masonry strength, vertical and horizontal reinforcement percentages, loading conditions, etc.). An analytical model that has been verified and validated with a series of complimentary tests is ideally suited to provide the element properties for the SCMs and LPMs.
