摘　　要：利用静力平衡方程,求解了外荷载作用下双模量矩形玻璃的中面位置,考虑了单层玻璃受力时的中面拉力;同时研究了外荷载作用下中空玻璃空腔体积改变与空腔内气体压强的关系;利用静力平衡方程、几何变形方程及物理方程,推导出了内、外层玻璃的挠度微分方程,建立了反映中空玻璃内、外层之间传力性能的中空玻璃的挠度计算公式,并将考虑中空玻璃内、外层之间传力的理论计算结果、规范公式计算结果与有限元计算结果进行比较。研究结果表明:考虑中空玻璃内、外层之间传力的理论计算结果是可靠的。The neutral plane position of double modulus rectangular glass under external load was solved with the static equilibrium equation,in which the neutral plane tension of single-layer glass was considered;the relations between the volume change of insulating glass cavity and the gas pressure in the cavity under external load were studied;the deflection differential equation of inner and outer glass was derived with the static balance equation,geometric deformation equation and physical equation,and the deflection calculation formula of insulating glass reflecting the force transfer performance between inner and outer layers of insulating glass was established.The theoretical calculation results considering the force transfer between inner and outer layers of insulating glass were compared with those obtained by standard formula and the finite element.The results showed that the theoretical above was reliable.
