Differences of snow pressure on partial sloping forms

Abstract

Differences of snow pressure on partial sloping forms were measured with ferroconcrete piles which have two strain gages on the inside and outside of base portion for three winters 1990/91 to 1992/93 at a snowed forest. The annual maximum snow pressure was 6.4 tons on a concave slope and 3.5 tons on a convex slope. Generally, snow pressure on partial concave slope was twice or more times larger than that on convex slope. It was suggested that planting of cryptomeria trees on partial convex slopes will aid to avoid snow damage to the trees.
