Research on Mechanical Properties of Inner Sleeve Connected Joint Between Modules of Fabricated Modular Steel Frame
Wenshuang Wu, Yan Wang
2023, 38(3): 1-12. doi: 10.13206/j.gjgS23010301
Abstract:
The finite element numerical simulation of the inner sleeve connected joint between the modules of the fabricated modular steel frame was carried out. The influences of the gap between the inner sleeve and the column wall, the thickness and the lengt...
Experimental Research on Post-Fire Mechanical Properties of Domestic Q355 Steel After Cooling from High Temperature
Chuntao Zhang, Hai Li, Wei Yu
2023, 38(3): 13-23. doi: 10.13206/j.gjgS22110104
Abstract:
As a new type of steel, Q355 has been widely used in the field of construction due to its excellent mechanical properties. However, it has the fatal disadvantage of poor fire resistance, which is dangerous to steel structure buildings. Through the sa...
Analysis of Mechanical Properties of Joints and Frames with Cantilevered Beams Based on Joint Simplification Theory
Zhenhai Shi, Minglan Han, Yan Wang, Kuan Pang, Xu Wang
2023, 38(3): 24-33. doi: 10.13206/j.gjgS22120501
Abstract:
To improve the efficiency of finite element numerical calculation of steel frame solid structure, the simplified theoretical model of joint was used to simplify the assembled embedded joint with cantilever beam, the assembled reinforced embedded join...

Hongliang Xiu
2023, 38(3): 34-42. doi: 10.13206/j.gjgS23010201
Abstract:
In order to further study the failure mode and mechanical characteristics of large diameter stud in ultra-high performance concrete (UHPC) and normal concrete (NC), the push-out tests of 7 groups of specimens were carried out. The influences of concr...
Construction Technology
Research on Refined Installation Management of Fully Dry-Connected Prefabricated Slab Based on BIM+3D Laser Scanning Technology
Ailin Zhang, Lan Tao, Xinxia Li, Yanxia Zhang
2023, 38(3): 43-50. doi: 10.13206/j.gjgS23012101
Abstract:
The fully dry-connected prefabricated slab completely avoids wet work on the construction site, which can make full use of the advantages of short construction period and environmental protection of the steel structures. However, due to the feature o...
