Abstract:For high-rise building structures with inclined columns, braces and conversion truss, tilt components lead to great tension in the plane of the floor in horizontal direction under vertical load. However, in the floor design of high-rise building structure, effect of vertical load on in-plane tension of the floor is not considered. A frame with mega columns and tilt bracings and reinforced concrete corewall high-rise structure in Shenzhen was used to analyze the reason of great tensile stress on floor under the gravity action, and the combined measure of “release“and “resistant” was provided as well as design suggestions.

Keywords:in-plane tension; vertical load; combined measure of “release“and “resistant”
