钢框架-聚苯颗粒混凝土灌注墙抗侧力试验研究

EXPERIMENTAL RESEARCH ON THE LATERAL RESISTANCE OF STEEL FRAME CAST-IN-PLACE WITH POLYSTYRENE PARTICLE CONCRETE WALL

保温装饰一体化聚苯颗粒混凝土灌注墙是适用于钢框架结构的一种外围护墙体。对填充了保温装饰一体化聚苯颗粒混凝土灌注墙体的钢框架结构和无填充墙体的框架结构进行了低周反复荷载下的试验研究和对比分析。试验结果表明:钢框架-聚苯颗粒混凝土灌注墙有良好的抗水平地震能力和耗能能力,其承载能力和侧向刚度显著提高,在相同变形时,能量耗散系数比无填充墙框架结构提高约75%。对2个试件进行了有限元分析,并与试验结果进行对比,两者吻合较好。

The insulation decorative integrated wall poured with polystyrene particle concrete is an envelope wall,which is suitable for steel frame structure.A steel frame poured with polystyrene particle concrete wall and another steel frame without poured wall were studied under quasi-static loading.The experimental tests showed that the frame with the wall had a good level of anti-earthquake capacity,energy dissipation capacity,its bearing capacity and lateral stiffness increased significantly,and the energy dissipation coefficient increased about 75%compored with the non-filled wall prame structure at the same defamation.The two specimens were simulated by finite element method,and the calculating results agree well with the experimental results.
