A CONTRIBUTION TO THE PROPER ASSESSMENT OF THE STRENGTH AND STABILITY OF TREES

Summary Prior to making any definite statement about the strength and stability of trees, exact details of occurring loads must be known, usually wind loads, the maximum stresses caused by these loads in the various parts of a tree and the anchorage potential of the roots. Previous methods of determining the condition of a tree, such as taking core samples and computer technology, in so far as they are relevant to TREE STATICS and a new non destructive type of survey method are discussed. The question of using supports to increase the safety factor against rupture or destruction is considered at the end of the paper.
