Seismic behavior

The modulus reduction and damping curves represent the nonlinear behavior of soil under cyclic load. In the literature, those curves were produced from lab tests of soil at particular confining stresses. This study developed a set of parameters that can be used to normalize the modulus reduction and damping curves to be stress-independent.

This paper presents a numerical analysis of the seismic behavior of square concrete filled steel tubular (CFST) columns. Finite element analysis (FEA) models in ABAQUS software were used to simulate a series of columns subjected to axial compression and cyclic lateral loading.

This paper addresses the strength and deformation capacity of slender columns retrofitted by externally bonded Carbon Fiber-Reinforced Polymers (CFRP) subjected to seismic loading. The behaviour of RC columns depending on the CFRP confinement (carbon CFRP jacket) and on flexural reinforcement (carbon plates) was analysed by a nonlinear finite element method based on multilayer shell element and multifiber beams with plasticity and damage models.
