中文摘要：

试验研究钢型材插入式泡桐木夹层结构平接胶结节点的抗弯性能，包括荷载．变形特性、应变发展规律和破坏模式。平接胶结节点采用工字钢型材，型材翼缘取3种不同内斜角，考察内斜角对平接胶结节点强度的影响规律。试验研究表明：平接胶结节点能够满足建筑结构变形限值所对应的承载力要求，该平接胶结节点形式可以应用于泡桐木芯材夹层结构：连接工字钢型材的翼缘内斜角对连接强度影响不明显。分析了胶结节点的变形特性、破坏机理和强度影响因素。研究成果可供复合材料夹层板结构的钢型材胶结节点设计应用参考。

英文摘要：

Experimental studies on flexural performance of adherence shaped steel joints for composite sandwich plates were carried out, including load-deformation behavior, strain development and failure modes. The I-shaped steels used for adherence joints have 3 different inside declining angles, whose effects on joint strength were studied. The tests show that the adherence joints can satisfy the loading-capacity requirement corresponding to the deformation limit of building structures, and be applied to paulownia wood core composite sandwich structures. The effect of inside declining angle on connecting strength was slight. The deformation behavior, failure mode and effect factors on strength were discussed. The results could be referred to for design and application of adherence shaped steel joint for composite sandwich plates.
