Research on Mechanical Properties of Truss String Structure with Spring Rods
Xiaodong Feng, Shengwei Liu, Weijia Yang, Yaozhi Luo
2021, 36(7): 1-8. doi: 10.13206/j.gjgS20042502
Abstract:
Ordinary truss string structures have been widely used in many practical projects and achieved good economic benefits because of its advantages known as reasonable distribution of stresses, light weight and convenient construction. However, the wind ...
Seismic Performance of Steel Frame-Coupled Steel Plate Shear Wall Structures with Different Coupling Ratio
Zhicheng, Tan Lin, Chen Yi Wu
2021, 36(7): 9-17. doi: 10.13206/j.gjgS20051501
Abstract:
Coupled steel plate shear wall is a new type of lateral force resisting system which is formed by connecting two steel plate shear walls with coupling beams. Through the interaction of coupling beam and wall limb, the capacity of resisting overturnin...
Fracture Prediction and Analysis of Q690D High Strength Steel Based on Cyclic Void Growth Model
Jianzhou Ge, Xuewei Huang, Jun Zhao, Wei Zhao, Chenchen Wei
2021, 36(7): 18-28. doi: 10.13206/j.gjgS20061103
Abstract:
High strength steel has been gradually applied in practical steel structures. The ultra-low cycle fatigue fracture analysis of steel is the basis to evaluate the fracture failure of high strength steel structures under strong earthquake. The traditio...
Finite Element Simulation Analysis of Lifting Point Arrangement and Support Unloading of Long-Span Roof Truss
Yongqiang Qiao, Taiyuan Guo, Qing Hu, Dongze Song
2021, 36(7): 29-34. doi: 10.13206/j.gjgS20031801
Abstract:
A long-span circular truss structure with a steel structure roof span of 66 m in a theater was considered to be divided into four unit structures due to construction conditions, and the unit structure is assembled on the ground and hoisted as a whole...
Study on Equivalent Thermal Resistance of Fire Protection Coating of Tension-String Truss Structure Under Fire
Guoan Yuan, Guozhi Qiu
2021, 36(7): 35-42. doi: 10.13206/j.gjgS21010802
Abstract:
In order to study the safety distance between the fire source and the steel members directly above the tension-string truss structure in a fire and the minimum value of equivalent thermal resistance Ri of fire protection coating, the temperature fiel...
