ESTIMACIóN DE LA RIGIDEZ A FLEXIóN Y CORTANTE DE MUROS

this article presents an identification method for the assessment of flexure and shear stiffness of shear wall buildings. required data includes an initial (theoretical) model, the estimation of lumped mass values (by floor) and the experimental evaluation of one or two eigenvalues (modal frequency and its modal shapes). the method estimates stiffness whenever flexural (ei) or shear (ga) values are relevant or are irrelevant. an initial formula includes both shear and flexural components. furthermore, particular developments are carried out for particular cases of irrelevant shear or flexural deformations. developed methods concern shear wall buildings with regular slabs . it′s application allows the identification of the system′s stiffness, and the presence of damage or changes in the initial stiffness. the method is applied for three numerical examples showing its simple implementation. numeric errors are null.
