▎ 摘　　要

NOVELTY - The method involves processing a test piece and carrying out cross-grain anti-pressure mechanical performance test. A load-displacement curve is set in a full time course of a wood transverse-grain pressure-resistant mechanical property test as three stages. A first stage line elastic section in a process of a transverse striation compression resistance. A second stage platform section and a third stage compact section are defined by a straight line. A stress and strain relationship straight line is determined based on an energy equivalent principle. A constitutive relation of the wood cross-graphene pressure-resisting full-time program is determined according to the relationship. USE - Method for constructing wood transverse grain pressure-resistant full-time-distance constitutive relation for precise quantitative safety evaluation of ancient building wood structure and modern wood structure. ADVANTAGE - The method provides a full-time constitutive relation capable of accurately and quantitatively evaluating wood cross-grain compression for safety of ancient building wood structure and modern wood structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the method for determining the overall relationship between the cross-grain anti-pressure mechanical properties of the wood involved in the method.
