Abstract
The purpose of this research is to gain the reasonable method to know the strength of building elements against existing impact loads. For this, we tried to analyze existing impact load (by human action, the flyings in wind and others) and reaction of building materials (glass, asbestos-cement board plywood, and others) against some different kinds (in mass, velocity and capacity of energy absorption) of impact load. Then basing on this analysis, we suggest a method to know whether a building element is proof against a kind of existing impact load. The contents of this research are as the following. 1. The process of Research 2. Analysis of the Existing Impact Load 3. Reaction of Boards Against Impact Load. 4. Method to Judge the Strength of Building Elements Against Impact Load
