Our country is situated at two big tectonic plates intersection, so frequencies of theearthquake in the history is very high, and the regions of high earthquake frequencieshave also suffered the massive loss. In china, most rural buildings are masonry structure.Because the earthquake resistance performance of masonry structure is very bad, thedestruction of masonry structure is very serious in earthquake.As one new kind of brick masonry, our country recently promotes its application.The concretes porous brick has its superiority, comparing to solid clay brick. Its weight ismuch light, and its producing can make very minor destruction to environment. So it hasvery big potential and development prospect, and it has the considerable economicefficiency and the social efficiency. Therefore, there is the necessity to conduct thecomprehensive research to the concrete porous brick material performance and itsmasonry wall performance, so the concrete porous brick can be promoted in theearthquake regions.It first carries on certain statements to the masonry structure’s performance in mostprevious big earthquakes, and it also analyzes the masonry structure’s destruction styleunder the earthquake function destruction style. Moreover, my paper also has carried onthe simple introduction of the topic, and discusses the recent development of the masonrystructure aseismatic measure. It also introduced the present domestic study aboutexperimental studies.It mainly establishes the finite element models of the concrete porous brick masonrywall, and then carries on the numerical simulation analysis of the models. It focuses oninspecting ratio of height and wide, the vertical pressure and the structure column’sestablishment. In analysis processing, the paper changes the value of these parameters.The analysis obtains the masonry wall’s function response under vertical and the lateralload, and analyzes obtains the present paper research conclusion through the analysis ofbricking-up wall’s load-displacement curve. The results show that: with the increases of increases, the bearing capacity and deformation capacity of the wall decreases; theincreases within a certain range of the vertical stress can increase the ultimate bearingcapacity of the wall, and the deformation capacity of the wall becomes worse; the set ofstructural columns and ring beam system can significantly improve the lateral bearingcapacity and deformation capacity of masonry walls.Finally, the paper carries on the evaluation to numerical simulation’s result, andpoints out some insufficiencies and the flaws in the paper, and proposed direction andcontent of the later research can penetrate, and the following researchers may performfurther studies and improve the research.
