Analysis and Calculation of Large Span Dry-Coal Shed

Abstract

The project of Wuhan Group Kunming Iron and Steel Co., Ltd., Promote the supply side structural reform and implement the special upgrading project of environment comprehensive raw material yard project ore yard (A to B) reticulated shell structure Located in Kunming Steel New Area, Cao pu Town, Anning City, Kunming City, Yunnan Province, 780m long, 50m high, the span is 147m (more than 120m), According to «Code for Seismic Design of Buildings» and «Technical points of special review on seismic fortification of high-rise buildings beyond the limit», it belongs to the out of gauge large-span space structure, Special review of engineering seismic fortification is required. The structural analysis of the project adopts SAP2000, MST2020, MIDAS Gen three kinds of software for calculation and analysis, And the individual model and the whole model are established respectively, Envelope analysis is carried out for two cases. Through linear elastic analysis, response spectrum small earthquake analysis, Medium earthquake analysis of response spectrum, elastic time-history analysis of small earthquakes, dynamic elastoplastic analysis of large earthquakes to analyze and calculate the deformation of latticed shells and the stress of membersl. Through a series of structural analysis and structural measures, To ensure that the reticulated shell and the lower part are coagulated on the short column and all performance indicators can meet the specification requirements. Through the structural analysis of two calculation models, ensure that all performance indicators can meet the specification requirements.
