胶合木梁与整体木梁力学性能的数值分析

NUMERICAL ANALYSIS ON MECHANICAL PROPERTY OF GLUED TIMBER BEAM AND INTEGRAL TIMBER BEAM

胶合木是一种在一定条件下将单独的规格材经胶合层压而成的结构用材,可有效利用强度高但尺寸小的木材制作不同形状和尺寸的大型结构构件。为研究叠合后的层板与整块木材强度的区别,采用ABAQUS有限元软件对木梁等构件进行数值模拟,分析对比两者抗弯、抗压等力学性质的差异。

Glued wood is a kind of structure material made from single sized lumber by gluing and lamination under certain conditions. It could effectively make timber with small size by high strengthen into large structural components of different shapes and sizes. To research the strength difference between laminated plate and whole timber, ABAQUS finite element software was used for numerical simulation of timber beam, and then their differences in mechanical properties, such as bending resistance and compression resistance, etc., were analyzed.
