摘要:
 根据实际工程需要,对足尺铁杉3层CLT板的单元结构进行了力学性能计算与分析。一方面,通过运用机械组合梁理论,对铁杉3层CLT板的有效弯曲刚度和弯曲强度等力学性能进行预测计算;另一方面,依据其计算结果对铁杉3层CLT板在实际工程应用中的挠度、所承受的弯矩和振动固有频率等结构性能进行了预测研究。结果表明,2个等级的CLT有效弯曲刚度、抗弯强度和振动性能等结构力学性能均能满足实际工程应用需要。上述以期通过对足尺3层CLT板的单元结构的力学性能设计计算与分析,有助于为我国大幅面装配式重型木结构建筑提供合适和可靠的配套墙板和楼板。
Abstract:
 According to the needs of practical engineering,the mechanical properties of the unit structure of the three-layer cross-laminated timber (CLT) board of full-size hemlock were calculated and analyzed.By using the mechanical composite beam theory,the mechanical properties such as effective bending stiffness and bending strength of the three-layer CLT plate were predicted and calculated.Based on the calculation results,the structural performance of the three-layer CLT slab in actual engineering applications such as deflection,moment of bending and natural frequency of vibration was predicted.The results showed that the two grades of CLT could meet the practical application needs,such as effective bending stiffness,bending strength and vibration performance.The calculation and analysis on the mechanical properties of full-size three-layer CLT plate structure would help to provide suitable and reliable supporting wall panels and floor in the large-scale assembly of heavy-duty timber buildings.
