Design And Mechanical Performance Of Assembled Cold-Formed C Steel Mongolian Yurt

Mongolian yurt is a national symbol of the grassland area and an embodiment of the grassland culture.Under the current environment of promoting green buildings and protecting grassland ecology,it has become an important issue to study mongolian yurts with light weight,standardization and large space.The cold-formed thin-walled C-shaped steel structure system is light,high-strength and easy to connect.The advantages in low-rise buildings are very obvious.This paper inherits and absorbs the essence of traditional architectural culture,and constructs a large-span yurt with C-shaped steel as the main component.The main research contents and conclusions of this paper are as followsFirstly,the yurt that can be assembled is designed by using the C-shaped of the two-legged steel,and a new type of node and yurt-skylight with easy installation and simple structure are proposed.Combine a calculation method suitable for the design of the yurt frame,and design and calculate the components of the yurt.Secondly,the low-cycle reciprocating load test of the yurt space rigid frame of the scale is carried out.The results show that the cerebral cerebral and the nodes have certain stiffness guarantee and reliable transmission force;the temperament coefficient of the yurt is 8.35,and the displacement deformation ability is more prominent;The bearing capacity degradation coefficient is above 0.97,the bearing capacity degradation is very stable;the energy dissipation coefficient is between 1.22 and 1.52,and the equivalent viscous damping coefficient is between 0.19 and 0.24,indicating that this type of assembled yurt has a higher load ability and seismic capacity.Finally,the yurt parts warehouse is constructed,the components of the yurt are coded and dimensioned,the requirements of menu design are realized,and the finite element analysis of all the yurts with certain parameters is carried out to ensure the reliable carrying capacity of the yurts with partial design.In this paper,the theoretical calculation,experimental research and finite element analysis of the assembled C-shaped steel yurt space rigid frame are carried out,and the yurt parts warehouse under common span and height is obtained,which can provide theoretical reference for the assembled yurt factory production.
