A Study Of Antiseismic Behavion Of Masonry Brick Building Reinforced By Expansion Web

With the flying development of society and economy, the architecture industry , the structure reinforcement technique and reinforcement materials flourish unparalleled. However, as a new kind of antiseismic structural materials adjusting to the high development nowadays, although has been widely used in bridge construct and decoration building , ect ,expansion web is still lack of studying on its antiseismic behavior.Aimed at this instance, professor Wankang Luo of Chongqing Jianzhu University has processed much elementary research on antiseismic capability advancement of expansion web on masonry brick building. The article has researched the form and mechanization of failure, crack resistance and bearing capacity, ductility, energy dissipation, hysteretic behavior, deformation, ect , through test to contrast models with rate 1:2 reinforced by expansion web and steel web .The result of the study has testified it an efficient measure to lay expansion web into masonry brick building for entirely improving antiseismic strength. Simultaneity, through contrast analysis validate that antiseimic capacity of expansion web is better than that of steel web. Therefore, based on the experiences summed up by precedence, the formulation for calculating the crack load and limit load of brick masonry house reinforced by expansion web is advanced, which provides project reference.Based on the analysis and studies of masonry shearing strength, test of prestressed single brick masonry wall, and test of prestressed brick masonry house models, and ect, the article has carried through several aspect research as below:1.A series of experiment on material capability of expansion web, including intensity of single thread and expansion web, ect;2.Research on influence of loading and destroy of masonry brick building reinforced by expansion web under lowcyclic loading;3.Study of impact of expansion web on ductility, energy dissipation, intensity ,ect under the same situation as above;4.Put forward computation formulation of masonry brick building reinforced by expansion web.
