摘要
目的开发一种轻质、高强、抗震、环保型建筑结构构件应用于我国地震区,以提高地震区建筑物的抗灾害性能.方法利用胶粘剂把竹材人造板与冷弯薄壁型钢复合成为楼板、墙体、梁等钢-竹组合构件,分别进行受弯性能试验和拟静力试验,模拟地震作用下组合构件的受力变形.结果钢-竹组合墙体的荷载-位移滞回曲线饱满,延性系数、耗能系数最高分别达到了2.47和0.865,抗震性能指标较高;钢-竹组合楼板最大的极限荷载值为29.63 kN/m2具有很高的承载力和较高的刚度,若截面设计合理构件破坏前的预兆明显,具有很好的延性;钢-竹组合梁在85 kN的荷载下仍没有破坏,具有较大的抗剪能力储备,荷载作用下的弯曲变形明显,破坏过程典型,可布置塑性铰.结论钢-竹组合构件是抗震性能优良的轻质、高强型组合构件,适合于地震区建筑结构中应用,具有巨大的市场潜力和广阔的应用前景.
To improve the seismic performance of buildings in the area of anti-disaster in China earthquake zone,the paper develops a lightweight,high strength,anti-seismic,environment-friendly building structural member.Bamboo plywood and cold-formed thin-walled steel through adhesives are combined into slabs,walls,beams and other bamboo-steel composite members.Through the bending test and quasi-static test,the failure characteristic,failure mechanism and bearing performance of composite members are studied.The results showed that seismic performance of bamboo-steel composite walls is excellent,especially ductile index and dissipative coefficient reach 2.47 and 0.865 respectively.Bamboo-steel composite slabs can provide high bearing capacity up to 29.63 kN/m^2.If the design of cross sections is reasonable,composite members show high ductile index and clear failure features.Bamboo-steel composite beams have large reserves of shear capacity,and under 85 kN load the best of that is still not damaged,at the same time under load they show obvious deformation process and typical damage process.Furthermore,plastic hinge can be arranged freely.Both of test results and theoretical analysis indicate bamboo-steel composite members are excellent seismic performance of high-strength members,which have huge market potential and development prospect.
