Study on Seismic Effect of Blocks Filled in Multi-Ribbed Composite Wall

Abstract eng:
Earthquake, which breaks out abruptly and unpredictably, is seriously threatening the safety of people’s life and possessions. As China is an earthquake-prone country, it is of great importance for us to exploring new damage-reduction methods. Multi-ribbed composite wall structure (MRCWS) is a new type of structure which has certain advantages in light weight and seismic performance, and multi-ribbed composite wall (MRCW) is the main bearing component of MRCWS. In this paper, first of all, the constitution and characteristics of MRCWS is simply introduced. And then based on the former experiment, comparisons are made between the wall filled and unfilled with blocks. After that, with FEM analysis applied, the FEM model of MRCW is proposed and the energy-dissipation rate of each part is calculated. It draws the conclusion that the blocks play an important role in strengthening the bearing capacity, stiffness and dissipating the input energy, which indicates that they are beneficial to the seismic performance of MRCW.
