Analysis of lateral capacity of R.C structure induced by infills wall

Specification of the reinforced concrete frame and reinforced concrete frame-shear wall,slab-column-shear wall,frame-the core tube of elastic story drift limit requirements,is based on previous experimental research and practical engineering statistics,and other reinforced concrete structures is carried out according to the results of the two degree of tightening or relaxation,and has yet to regulate short-pier shear walls on elastic story drift limit requirements.In this paper,the commonality of the structure before,find the wall is filled with limit values affect an extremely important factor.Filled wall as an important part of the structure can bear part of the level of seismic action,to improve the structure lateral stiffness and to limit the deformation of the main structural elements.At design time,often through the cycle reduction factor to consider its effect on the structure,but this calculation does not meet the actual situation of the horizontal displacement calculated displacement.Through some experimental results and theoretical analysis,paper propose that design with stiffness increased flexibility in the calculation method to calculate the horizontal displacement angle,and propose special shaped column frame and short shear wall structure of the elastic story drift limit of the value can limb thickness ratio of 1/550 and 1/800 the difference between linear.
