Hybrid-design high-strength steel honeycomb composite beam
A hybrid-design high-strength steel honeycomb composite beam comprises a concrete floor and a section steel honeycomb beam, the section steel honeycomb beam is composed of an upper flange, a web and a lower flange, the section size of the upper flange is consistent with that of the lower flange, and a plurality of through holes are formed in the web in the length direction of the beam to form a honeycomb structure. The concrete floor and the upper flange are attached and connected through the shear connectors to form a synergistic whole, and steel plates adopted by the upper flange and/or the web and the lower flange are different in strength. Due to the fact that the composite beam mainly plays a role in bending resistance in the structure, and the upper flange and the lower flange are mainly used for bending resistance in the profile steel honeycomb beam, the strength of the steel plate can be reduced under the condition that the size of the web is not changed, steel plate materials with high-grade strength are saved, and the utilization rate of the materials is improved. The lower flange adopts the steel plate with higher strength than the web, so that bearing capacity weakening caused by the through holes in the web can be compensated, the strength and the overall bearing capacity of the honeycomb composite beam are improved, the steel consumption is not increased, and the self weight of the structure is reduced.
一种混合设计高强钢蜂窝组合梁，包括混凝土楼板和型钢蜂窝梁，型钢蜂窝梁由上翼缘、腹板和下翼缘组成，且上翼缘与下翼缘的截面尺寸一致，其中腹板上沿梁长度方向开设若干通孔形成蜂窝结构，混凝土楼板与上翼缘贴合并通过抗剪连接件连接形成一个协同作用的整体，上翼缘和/或腹板与下翼缘采用的钢板强度不同。由于组合梁在结构中主要发挥抗弯作用，型钢蜂窝梁中进行抗弯的主要是上翼缘与下翼缘，因此可在腹板尺寸不变的情况下，降低其钢板强度，从而节省高等级强度的钢板材料，提高材料利用率。下翼缘采用比腹板强度较高的钢板，可弥补腹板开通孔造成的承载力削弱，在提高蜂窝组合梁强度与整体承载力的同时，不会增加钢材用量，减轻结构自重。
