Abstract:Design objectives and corresponding specifications of the progressive-collapse resistance in different codes of foreign countries are introduced. Based on a number of calculations, with the consideration of the actual structures designed according to Chinese codes and the design objectives for Chinese structures, the design methods for the progressive-collapse-resistance of Chinese RC frame structures are proposed, which include conceptual method, tie force method and alternate load path method, together with corresponding detail design requirements.

Keywords:frame structure; progressive-collapse-resistance; tie force method; alternate load path method; detail design
