Abstract |
Since 1990s, the construction of tall buildings has been increased greatly. For the tall buildings, the story height is an important factor to accomplish economic buildings. Several researchers including authors have studied for the structural systems reducing a story height of the buildings. A structural system consisting of concrete filled tube column and flat plate slab is one of the story reducing structural systems, in which each element has been used as an efficient component for tall buildings. However, the structural behaviour of the joint has to be clearly explored. Therefore, the finite element analysis method is used to verify the stress concentration, load flow and excessive deformation on the joints. Three types of joint details are compared and the better one is obtained. The design equation for the adopted joint detail is also proposed by the FEM analysis. |
