Abstract

<p>The objective of this study is to investigate the punching shear strength and mechanism of flat slab structure with steel column and steel capital in RC slab based on FEM analysis results. Modeling for FEM analysis on the inner column-flat slab specimens was verified showing agreements with the test results; thus, reliable analytical data on inner stress transferred on the critical sections at punching shear failure. In particular, it was found that the ultimate moment resistance at the column-slab connections attained the upper limit when the shear stress on certain critical section reached its strength.</p>
