基于BIM对型钢混凝土梁柱节点施工优化

Construction Optimization of Concrete Section Steel Structure Beam-column Joints Based on BIM

型钢混凝土结构常运用于超高层结构中,由于型钢混凝土柱其承载力是型钢、混凝土与钢筋三部分承载力的叠加,因此具有变形能力强,抗震性能好、用钢量较省、受力较合理等特点,但在施工过程中梁筋与型钢混凝土柱的连接布置是施工难点,本文运用BIM三维软件对型钢混凝土柱与梁筋的连接布置进行三维施工可视化与型钢和钢筋进行碰撞检测,并对型钢结构梁柱节点连接布置进行优化,并据此与设计单位进行沟通,达到方便施工,指导施工的目标。

Concrete section steel structure is often used in high-rise structures,due to the bearing capacity of section steel concrete column is superposition of the bearing capacity of section steel,concrete and reinforcement,it has the characteristics of strong deformation ability,good seismic performance,save material of steel and the stress is more reasonable. But it is difficult to connect beam reinforced with section steel concrete column in the process of construction. This paper uses 3d software of BIM for three-dimensional construction visualization of the junction of section steel concrete column and beam reinforcement,for collision detection of steel and steel rebar,also for optimization of connection and arrangement of section steel structure beam-column joints. According to this to communicate with design unit,to achieve convenient construction and guiding construction goal.
