摘要

本研究的目的是建立两圆孔胶合层合木梁劈裂强度的设计方法。本文提出了一种劈裂强度的设计方法，该方法利用有限元分析的方法，计算出随着孔间距离的减小，垂直于孔周围晶粒的最大拉应力之比。然后，对带两个圆孔的胶合木梁进行三点弯曲试验，并将试验值与计算值进行对比，验证了所提设计方法的有效性。

STUDY ON STRENGTH OF GLUED LAMINATED TIMBER BEAMS WITH TWO ROUND HOLES

The purpose of this study is to establish a design method for the splitting strength of glued laminated timber beam with two round holes. In this paper, a design method for splitting strength is proposed by formulating the ratio of the maximum tensile stress perpendicular to the grain acting around the hole as the distance between the holes decreases, using finite element analysis. Then, a three-point bending tests were conducted on a glued laminated wood beam with two round holes, and the experimental and calculated values were compared to confirm the validity of the proposed design method.

期刊介绍： The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
