Fiber요소와 전단스프링을 이용한 철근콘크리트 전단벽 모델의 사용성에 대한 연구

초록

Fiber elements and a spring are used to predict behavior of a wall. The fiber elements and the spring reflect flexural behavior and shear behavior respectively. The parameters of spring which represent pinching effect and decrease of loading and unloading stiffness are determined by comparing VecTor2 and OpenSees. To study the serviceability of the spring, reinforced concrete buildings containing a shear wall are evaluated using nonlinear dynamic analysis with various aspect ratio(H/L) of wall and height of beam. The aspect ratio of the wall has relationship with difference between interstory drift ratio of model with spring and interstory drift ratio of model without spring. On the other hand, the height of beam doesn't have the relationship.
