Abstract
This paper describes an influence of composite effect of concrete slab on both mechanical characteristic and earthquake response of frames. The influence of composite effect was examined by comparing three kinds of analytical methods. As a result, it was observed that the effect of concrete slab had great influence on natural period of the frames, ultimate base shear coefficient, and maximum story drift angle. It was clarified that they could be estimated only by considering increase of flexural stiffness of steel beams.
