An Experimental Research On Hollow Shear Wall Of R.C. Structure With Seams

With the alteration and innovation of traditional building technique and implemention of the policy on walling material and energy saving, the development of the residential structure system becomes one of the pre-task in engineering at present. So,considering that the traditional cast-in-situ R.C.shear wall structure has such disadvantages as large self-weight, stiffness and seismic forces, poor ductility and energy wasting, the subject puts forward a new type of hollow shear wall of R.C.stucture with seams which has the advantages of not only high bearing capacity but also small self-weight, stiffness and good ductility and so on.(1) In order to study the characteristics of the new-type structure , the psedo-dynamic and psedo-static test of one third-scale model six-storey building assembled with hollow shear wall of R.C with seams were conducted.(2) The structural dyanamic performances such as interal force, deformation and failure forms and so on under the horizontal earthquake action are discussed, and the regularity of the structural period, frequency, damping and other dyariamic behaviors in different stages are presented.( 3 ) The characteristics of earthquake response such as structural displacement, interstorey drift, earthquake action, the amplificatory coefficient of seismic action and the regularity of members'strain and the deformation property, the characteristics of hysteretic curve and the restoring force are analyzed.( 4 ) By theory of analogical ratio,the result of test under less alllst prototype is analyzed,and the deviation of parameter in different prototye is presented.(5) The relation of stiffness ratio of coupling wall-beam to coupled wall and ductility of coupling wall-beam is discussed..( 6 ) The primary economy-technology analysis are discussed.It is concluded that hollow shear wall of reinforced concrete structure with seams is a new kind of earthquake resistant and energy-saving structure.
