Abstract

 To propose a calculation method for snow loads that takes rainfall after snowfall into account, a rainfall experiment was conducted. Surcharge load increases continuously once rain starts falling, but the rate slows down once the eaves start discharging rainwater. The load reaches its peak once the rainfall intensity and flow rate at the eaves reaches equilibrium. This study tested a regression formula for surcharge load based on roof shape and snow depth. Also, this study evaluated a method for estimating the rain-on-snow surcharge load depending on regional weather conditions, and proposed a modified formula for surcharge load.
