摘要
针对动荷载作用下的夹层玻璃结构进行研究,在综合考虑中间胶片对其抗弯性能的贡献、玻璃的阻尼以及惯性力等多因素影响的基础上,基于小挠度变形理论建立了夹层玻璃在动荷载作用下的动力学方程.采用多尺度法求解得到夹层玻璃在主共振条件下的幅频响应方程;通过算例分析了动荷载、玻璃阻尼和结构几何参数对夹层玻璃振幅的影响.结果表明:玻璃阻尼、玻璃边长和厚度对振幅具有显著影响,而中间胶片厚度的影响相对较小.所得结果为夹层玻璃结构的设计与优化提供了重要参考,有助于提高其抗震和抗风性能.
Abstract
The laminated glass structures under dynamic loading,considering the combined influence of interlayer con-tribution to flexural performance,glass damping,and inertial forces were investigated.The dynamic equation of laminated glass under dynamic loading was established based on the small deflection deformation theory,taking into account multiple factors.The multiscale method was employed to obtain the frequency-response equation of laminated glass under the prin-cipal resonance condition.Case studies were conducted to analyze the effects of dynamic loading,glass damping,and struc-tural geometric parameters on the amplitude of laminated glass vibration.The results indicate that glass damping,glass di-mensions,and thickness significantly affect the amplitude,while the influence of interlayer thickness is relatively minor.These findings provide valuable insights for the design and optimization of laminated glass structures,contributing to en-hanced seismic and wind resistance performance.
