本文对应县木塔梁柱节点的结构性能进行了试验研究。制作了典型燕尾榫卯连接梁柱节点的缩尺模型并进行了试验研究。确定了接头的四种失效模式。这些包括垂直或平行于纹理的压缩下的组件的屈服，垂直于纹理的拉伸下的组件的断裂，和榫从榫槽拔出。通过试验观测，揭示了模型梁柱节点的结构性能，并基于相似理论，推导了宝塔原型梁柱节点的刚度和抗弯承载力。建立了利用梁柱节点结构性能估算柱框架开间侧移刚度和承载力的分析模型，并应用于评估塔的层间侧移性能。本研究从结构角度为应县木塔等文物建筑的保护提供了参考。(C)2015年美国土木工程师协会。
This paper presents an experimental investigation on the structural performance of the beam-column joints of Yingxian Wood Pagoda. A scaled model of typical beam-column joints with dovetail tenon-mortise connection was manufactured and tested. Four failure modes of the joint were identified. These included yield of component under compression perpendicular or parallel to grain, fracture of component under tension perpendicular to grain, and tenon pullout from mortise. The structural performance of the model beam-column joint was revealed from test observations, and the stiffness and the moment-resisting capacity of the prototype beam-column joints of the pagoda were derived based on the similitude theory. An analytical model for estimating the lateral stiffness and load-carrying capacity of a bay of the column-frames using the structural performance of beam-column joints was developed and applied to evaluating the inter-story lateral performance of the pagoda. This study provides reference, from a structural point of view, for the preservation of cultural heritage structures such as Yingxian Wood Pagoda. (C) 2015 American Society of Civil Engineers.
