Seismic performance is basically required in precast shear wall. This study focuses on evaluation and improvement on precast shear wall seismic performance. By carrying out the finite-element simulation on a precast shear wall spatial model with new connector from a practical high-rise precast residential building, which was named as NPGCS and experimentally tested by low-cyclic reversed lateral loads in early studies, the performance results including strengths, stiffness, stress, and concrete damage ratio distributions were obtained, and the reliability of NPGCS spatial model was verified. According to the testing results, the finite-element simulation for the NPGCS spatial model is reliable and relatively accurate, especially for applying contact and beam elements into numerical analysis of precast interfaces and dowel shear actions, respectively. The strengths, stiffness, stress, and concrete damage ratio distributions from the simulation also supported the experimental results and conclusions.

Concrete Damage Plasticity

The aim of this work is to show how the concrete damage plasticity model developed by Lubliner et al. can be applied for calculation of a motorway bridge collapse occurred in the Amur region, Russia. The concrete structural behaviour is highly complex. Being a quasi-brittle material, concrete demonstrates softening behaviour that is numerically complex due to the loss of positive definiteness of the tangent rigidity matrix of the material, and hence the loss of the ellipticity of the equilibrium rate equation. This eventually leads to the loss of well-posedness of the rate boundary value problem. Besides that, concrete behaviour in compression differs from that in tension. There are a few different failure modes of concrete material: tension cracking, compression crushing, spalling of concrete, etc.

Concrete Damaged Plasticity

A concrete damage model has been incorporated in finite element code ABAQUS as concrete damaged plasticity model to examine the sensitivity of the damage, as ABAQUS has the model that is capable of stiffness degradation in cracking which is the basis of fracture mechanics. Nonlinear constitutive relationships for concrete and steel have been incorporated in the model. The static and dynamic response of the structure at 10 different damage levels is studied and the sensitivity of the damage model towards the presence of non-linearity has been discussed. The concrete damaged plasticity model is capable of predicting formation of cracks in concrete beams against any kind of loads, as the results match with the experimental results. It can be concluded that the concrete damaged plasticity is a versatile tool for modeling RC structures and careful choice of solution procedures for dynamic analysis can lead to accurate modeling of concrete using a few routine laboratory test results of the materials.
