Research On The Design Method Of Public Building Frame Structure

Concrete frame structure system has good seismic performance,good economic index,less vertical components,flexible layout and high space utilization rate,which is widely used in industrial and civil public buildings.With the improvement of economic strength and the level of Architectural Science and technology,the function of architecture and the design of the model are becoming more and more diverse.These buildings have become more and more strict with the layout of space and structure.The structure of the long,irregular,large span and long suspension is often appeared,the conventional concrete frame cannot meet the design requirements.Based on the actual engineering case,this paper makes a theoretical analysis,finite element analysis,numerical calculation,and many other research methods,and obtains a reasonable solution,which not only solves the practical engineering problems but also has a certain reference value.In this paper,PMSAP software is used to analyze the stress and deformation of the long concrete frame structure,and the stress and deformation characteristics of the concrete frame are obtained;The ETABS software is used to analyze the structure of the irregular frame structure,and the seismic performance of the whole structure is evaluated,and the weak layer and weak part of the whole structure are found out and the corresponding measures are taken to strengthen;For large span frame structure of planting roof of three structure schemes for comparison and discussion,and through the software of SpaceCAD of long-span now cast in situ prestressed concrete hollow floor by simulating beam method for modeling and analysis,come to hollow floor system by force and deformation and the surrounding supporting the design points of the system support;For theatre,multi function hall and other public buildings in the framework of cantilever stand,from A theatre two-story bleachers suspended pick beam based,according to the characteristics of the project the variable cross-section cantilever beam scheme,and using ANSYS software in the stands of cantilever tapered beam of static and dynamic stress and deformation analysis.
