Research on Deflection of Insulating Glass Under Wind Load

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.
