Description

TECHNICAL FIELD

[0001] The utility model relates to civil engineering technical field more specifically, the utility model relates to a kind of inserted bolt connection beam column joint. BACKGROUND

[0002] Beam-column connection is the core hub of load transfer and collaborative stress bearing in building structure system, and its performance directly determines the stability and safety of the whole building. As the key load transfer joint of frame structure, beam-column connection not only needs to bear the vertical load transferred by beam components, including building weight, live load and equipment load, etc., but also needs to effectively distribute the complex internal force caused by horizontal load such as wind load, snow load and earthquake action. In modern engineering practice, joint design has evolved from simple geometric connection to a systematic solution integrating mechanical performance optimization, material efficiency improvement and construction feasibility.

[0003] Traditional rigid joints completely connect the beam flanges by welding or high-strength bolts, forming a continuous bending moment transfer path, which can effectively improve the lateral stiffness of the structure and meet the needs of high-rise buildings for wind vibration control. Semi-rigid joints allow limited rotation through specific connectors, which can not only release part of the stress concentration, but also dissipate energy through plastic deformation under seismic action, significantly improving the seismic toughness of the structure. For example, when using dog bone type weakened joint design, the local reduction of beam end section area can guide the plastic hinge to move outward and avoid brittle failure in the core area of the joint.
