Research On Engineering Application And Seismic Performance Of Reinforced Concrete Ctructure Of The Slope Roof

Reinforced concrete sloping roof in recent years more and more application in architectural engineering,form complex roof shape,but also to the design of such structures increases many technical difficulties,especially for large span roof(such as academic report hall,Auditorium)higher technical requirements.This thesis take Hunnan experimental middle school lecture hall of the main building as an example,analyzes the situation of this kind of structure stress under static and dynamic loads,provide reference data for the structure design.First of all,the section estimation according to the construction programme,,determine the load and static analysis using PKPM model,the internal force of beam and column is obtained,the cross section of the checking and reinforcement.According to the specification checking floor displacement of the structure,cycle index.Secondly,based on the static analysis,according to the specification of a total of 2 artificial earthquake wave and 2 natural waves,elastic dynamic time history analysis,to supplement the structural calculation of elastic deformation.Finally,using the software also selected 2 artificial earthquake wave and 2 natural waves on the structure of the elastic-plastic static and dynamic time history analysis,elastic-plastic deformation checking,find out the disadvantageous position of structure,and the development trend of plastic hinges,provide the design basis for design.
