摘要

试验对一片灌芯玻璃纤维增强石膏板进行了侧向力作用下的低周反复试验,得到了试验模型的裂缝分布特点、开裂荷载及极限荷载。分析表明:混凝土灌芯玻璃纤维石膏板受力时作为一个整体共同工作,结构通过纤维石膏板的开裂耗散能量,提高了结构的抗震性能,使结构具有较好的延性。灌芯混凝土玻璃纤维增强石膏板类似于有连接键的带缝剪力墙结构,具有良好的抗震性能。
One piece of glass fiber-reinforced plasterboard is tested under different axial loads. Crack distribution, cracking load and limit load of CFFRP are obtained under low-cycle loading. Testing results indicate that the concrete core and glass fiber-reinforced plasterboard work together to resist load effects, the earthquake energy is dissipated by the plasterboard cracking and the seismic behavior and displacement ductility are increased. This article draw a conclusion that the glass fiber-reinforced plasterboard fully filled with concrete is similar to the shear wall with slot.
