帮卅走学硕士学位论文ABSTRACT 帮卅走学硕士学位论文 ABSTRACT The high-rise building was inereasly developed recently,because of its excellent carrying capacity and seimatic behavior,shear wall structures were widely adopted．But,due to the Deficiency of the traditional Concrete Strength，the component has a great CROSS section,deadweight was added，and SO was the earthquake loads，and due to the great Cavity Volume Fluctuations of traditional concrete，it was prone to shriJll【’Chap．Along with the widely adoption ofsteel fiber concrete，the advantage ofsteel fiber concrete in increasing the carrying capacity,ductility,ability of energy dispassion and in reducing the stiffness degradation gradIIally appeared．But,enough treatment basis in theory and applications of the HPC shear wall with polypropylene fibers was still deficient,that affect seriously the development of this new type of Shear Wall Structures and locked the development and perfection ofthe theory of steel fiber concrete strcmre． In this dissertation,the load-bearing capacity,earthquake resistant behavior Was studied through the horizontal cyclic loading tests of eight steel fiber partially reinforced concrete shear wall．For deeply study the bearing capaci瓴ductility,behavior of dissipation seismic energy and the anti-erack performance of shear walls wim the concre把partially reinforced by steel fiber,these works as follows have been done． (I)H鲥zontaI cyclic loading tests was taken on eight steel fiber partially reinforced concrete shear wall with O．1 axial．the loading path,distribution and development of concrete crack were recorded in detail，And the load-bearing capacity,earthquake resistant behavior of steel fiber partially reinforced concrete shear walls were deeply studied． Experiment,a／results indicated Oat steal fiber caused obvious influence OR distribution and development ofcracks，and a notable one to the earthquake resistant behavior to the walls． (2)The impact ofthe thickness ofsteel fiber concrete on the bearing capacity,d
