SIMPLIFIED LOAD COMBINATION FACTOR FOR SNOW LOAD

The load combination factor for snow load is formulated by a simplifie d development based on Turkstra's rule for the load combination and th e Gumbel distribution for the snow load model. The probability of exce edance expression is compared with an existing probabilistic load mode l. The load combination factor is expressed in terms of the period of snow duration and the ratio between the standard deviation of the prin cipal load effect and the accompanying snow load effect. Numerical exa mples are presented and discussed with the load combination factor use d in Japanese current practice.
