摘要

参照美国标准ASTM D 5764-97a（2007）,探讨测试方法、层板等级、钢销直径和加载方向对日本落叶松（Larix kaempferi）胶合木销槽承压强度的影响。单因素方差分析结果表明,影响日本落叶松胶合木销槽承压屈服强度的因素依次为:层板等级>钢销直径>加载方向,测试方法对承压性能的影响不显著。

Abstract

Glulam samples made of Larix kaempferi wood were made and tested according to ASTM D 5764-97a（2007）.The following effects on dowel bearing strength were analyzed:test method,laminate grade,bolt diameter and loading direction.The influence factor order ranked by importance on dowel bearing was as follows:laminate grade>bolt diameter>loading direction. Test method had no influence on dowel bearing strength.
