摘要
提出一种集承重与节能为一体的新型剪力墙结构体系—节能环保型叠合板结构。通过二片节能剪力墙在水平低周反复荷载作用下的试验,考察了结构的裂缝开展、受力全过程和破坏形态,分析了墙片的变形性能、延性、耗能能力等抗震性能,探讨了格构钢筋的可靠性和受力机理。研究结果表明,节能剪力墙受力性能良好,具有较好的延性,剪式支架能够较好地连接两侧预制板,并与现浇层协同工作,可以保证节能剪力墙的整体工作性能。为节能环保型叠合板结构的工程应用提供依据。
A new shear wall structure system which integrates bearing and energy saving-energy saving and environmental protection superimposed slab structure is presented.Based on the low cyclic reversed lateral loading tests of two Energy-saving superimposed slab shear walls,review the cracking behavior,whole course under stress and failure form of the structure,analyze the seismic behavior of energy saving shear wall such as deformability,ductility and dissipation of energy,discuss the reliability of steel bar truss and its mechanism under stress.The experimental results show that energy saving shear wall bearing performance is good,good ductility,steel bar truss can better connects the two precast panels that work with cast-in-place concrete,which can guarantee the integral performance superimposed slab.That provides basis for engineering application of energy saving and environmental protection superimposed slab structure.
