STUDIES ON MECHANICAL CHARACTERISTICS AND MAXIMUM STRENGTH OF SHEAR-LAG

Abstract

 It is important to evaluate the strength and the behavior of shear-lag to clarify seismic margin of reactor equipments. However, there are a very limited number of experimental studies that focus on the mechanical characteristics of shear-lag. This study carried out the cyclic static load test and the simulation analysis, and evaluated the mechanical characteristics and the maximum strength of shear-lag. A half-scale specimen of a shear-lag and surrounding shear walls was used in the experiment. Elasto-plastic analysis was made using the three-dimensional finite element model.
