Analysis On The Damage Process Of Concrete Block Masonry Structures

Concrete small hollow block, which is in favor of environment and saving plantation, is a kind of wall material to substitute for clay block. It is not only lighter than brick wall in weight,which profit aseismic behavior of masonry wall, but also the speed of construction is quicker. In this paper, MCA nonlinear two-dimensional simulation software used for this block was composed of two aspects of simulation analysis:1. Structure model which have windows, and the numerical simulation on destructive process under different intensity earthquake effect are carried out,and the simulation results are consistent with the destruction condition of practical earthquake.2. The MCA method is used to model four typical foundation bed non-uniform settlement model in this paper. By imposing certain load on the top of masonry structure to simulate foundation bed's sedimentation,the simulation results are mercifully consistent with the practical situation,the reliability and accuracy of the research conclusion research conclusion are confirmed.The simulation results reproduce the earthquake cracks process of the formation and expansion process. The simulation results obtained with the literature data and consistent with the actual situation.Based on both simulation and some of the basic mechanical theory well explains the simulation results and practical engineering phenomenon, it offers definite directing or assigning role for practical projects.
