Retrofitting Effects of Seismic Resistance Capacity of Existing RC Wall Type Apartment Slab Structures
Jihyun Hwang, Taewon Park
Abstract
A need for seismic design of buildings have been increased dramatically due to the fact that seismic damages have been reported all over the world. In Korea, the seismic design code for buildings was developed in 1988. However, the buildings designed and built before 1988 are expected for serious seismic damages. With this reason, an appropriate seismic retrofitting method is required for such buildings, which needs to be economical and practical. In this study, seismic retrofitting methods by using H-section steel to the slab are developed and introduced applying to the wall-type apartment buildings. As a result, performance of slab test models was improved to satisfy the required retrofitting capacity. Stiffness and energy dissipation capacity of the model were also enhanced.
Key Words: Seismic Design; Seismic Retrofitting; Wall-type Apartment; Stiffness; Energy Dissipation
요지
최근 세계 곳곳에서 지진에 대한 피해가 보고되면서 적정한 수준의 건물 내진성능을 보유하기 위한 많은 노력이 진행되고 있다. 특히 우리나라는 1988년 이전에 설계되어 내진설계가 되어있지 않은 많은 기존구조물에 대한 대책마련이 시급하다. 이에 본 연구에서는 내진설계 되어있지 않은 리모델링 대상 노후 건축물을 보강하여 내진성능을 평가하였다. 이를 위하여 비내진상세를 갖는 노후공동주택을 모델로 하여 슬래브 보강실험을 수행하였으며 슬래브에 H형강으로 보강한 실험체는 보강요구값을 만족하였고, 강성 및 에너지 소산능력에도 우수한 결과를 나타내었다.
