Study On Antiseismic Behavior Analysis Of Light Steel Reinforced Concrete Shear Wall

With the development of modern economy, high building developing very fast. Light steel reinforced concrete shear wall is a type of new shear wall. It is gradually widely used in these years, because it is light and expedient when installed, with excellent heat preservation.In order to study mechanics capability and antiseismic capability of light steel reinforced concrete shear wall, based on elementary material stress-strain relation and some hypothesis, odd solid light steel reinforced concrete shear wall two-dimension plane analysis model which accord with actual structure characters and strength bear characters using finite element software ADINA. There are three group component models as follows: the ratio of height to width is 1.0,1.5 and 2.0, the range of the ratio of axial compressive stress to concrete strength is from 0.1 to 0.35, the range of vertical distributing steel ratio and lateral distributing steel ratio is from 0.1% to 0.2%, steel proportion of hidden pole is 452mm2,615mm2 and 804mm2; We analysis the reactions of models under these two circumstances: (1) model under vertical constant load and lateral monotony increase by degrees load, the process and forms of destroying, load capability and ductility; protract correspond load-displacement curves,relation curves of the ratio of height to width vs ductility, the ratio of axial compressive stress to concrete strength vs ductility, the ratio of distributing steel vs ductility, the proportion of hidden pole vs ductility. Particular analyze the effect of the ratio height to width, the ratio of axial compressive stress to concrete strength, the ratio of distributing steel and the proportion of hidden pole on displacement ductility and the grade of the effect. (2) hysterical curves of the models which under the vertical constant load and lateral low cycle reiteration load, analyze the effect of the parameters on energetic capability of light steel reinforced concrete shear walls. According to the advanced analysis some design advices are given.
