| With the peak of housing construction in China,the design task of architectural design institutes is becoming more and more arduous.In order to reduce design time and design workload,many design institutes will adopt simplified modeling method to design.In the design work,because of improper simplified modeling design,engineering accidents often occur.Therefore,the accuracy of simplified modeling calculation results is the necessary guarantee to prevent the design results from having potential safety hazards.Based on this,this paper studies the accuracy of simplified modeling calculation of general sloping roof structure.In order to simplify the analysis of sloping roofs in design institutes,a flat roof with half the height of the real sloping roofs is often used.Taking a single two-span frame as an example,this paper systematically studies the difference between simplified modeling and real modeling of sloping roofs with different heights,spans and slopes under basic intensity and rare earthquakes.Some guiding suggestions are put forward for simplified design.On this basis,the differences between simplified modeling and real modeling of space two-span frame are further analyzed.The main research work of this paper is as follows:(1)This paper discusses the current situation of research in this field at home and abroad,and puts forward the research work of this paper;(2)Taking a single two-span frame as an example,the differences between simplified calculation and actual situation of sloping roof structures with different heights,spans and slopes under rare earthquakes in Nanchang area are analyzed,and some suggestions for simplified modeling design are put forward.(3)Taking a two-span frame as an example,the differences between simplified modeling and real modeling are analyzed,and suggestions for practical simplified application are put forward.(4)The accuracy of research results is checked according to engineering examples.(5)Summarize the full text and put forward prospects. |
