摘要
提出了一种新型内嵌风管楼盖,通过静力试验研究了单向顺孔和横孔形式下,现浇内嵌风管楼盖的抗剪破坏形态和受力性能,并依据楼板破坏机理提出了针对该楼盖形式的抗剪承载力计算方法.研究结果表明:现浇内嵌风管楼盖的抗剪性能较优,顺孔楼板的抗剪承载力大于横孔楼板;顺孔楼板结构在达到峰值荷载前表现出良好的线弹性性能.此外,该类结构可用于暖通空调(heat,ventilating and air conditioning,HVAC)系统中,达到绿色环保、节约资源的整体效果.
A new type of air-duct-embedded floor is presented in this study.The shear failure modes and mechanical properties of a cast-in-place air-duct embedded floor with longitudinal and transverse holes were studied using static tests.Based on the failure mechanism of the floor slab,a shear-bearing capacity calculation method for this floor type was proposed.The results show that the shear performance of a cast-in-place floor with embedded air ducts is better,that the shear capacity of a floor with an along-hole is greater than that of a floor with a cross-hole,and that the structure of a floor with an along-hole exhibits a good linear elastic performance before reaching peak load.In addition,this type of structure can be used in heat,ventilating and air conditioning(HVAC)ground-source heat pump air-conditioning systems to achieve the overall efiects of green environmental protection and resource savings.
