Abstract:In order to protect the safety of urban drainage and based on the requirements for building design plane layout and function setting of wastewater treatment plant (WWTP), the structural styles of complex buildings in the partial WWTP of China tend to get more and more complicated and irregular. Therefore, the problems of exceeding limits are brought about in the structural design. In order to improve the seismic reliability and safety of over-limit construction projects, the time history analysis method should be used in the structural design to take the structural over-limit countermeasures of adding calculation under frequent earthquakes. And the special examination should be passed. Combined with an engineering example, the calculation methods and measures taken in the design calculation and analysis of the special-shaped column frame - shear wall over-limit multi-story buildings are mainly expounded.
