This paper investigates the seismic behavior of Pingshenke Dou-Gong bracket under the overhanging and width direction. Two full-scaled Dou-Gong brackets of Yihe Hall are tested by the pseudo-static test. The effects of loading direction on the failure patterns, hysteretic characteristics, stiffness and strength degradation, energy dissipation, and deformation capacity of the whole model under the overhanging and width loading direction are studied. Moreover, the rotation and shear displacement of Dou-Gong bracket components are discussed. The results indicated that when Dou-Gong bracket is loaded in the overhanging and width direction, the Da-Dou and Mantou-tenon are damaged. The Dou-Gong bracket loaded in the width direction has a higher bearing capacity, initial stiffness, and energy dissipation but a poor deformation capacity than Dou-Gong bracket under the overhanging direction. However, the stiffness and strength of both Dou-Gong brackets degenerate significantly. The rotation and shear displacement of the component increase with the displacement. The higher the upper components, the greater the rotation displacement, but the shear displacement is not obvious. When Dou-Gong bracket is loaded in the overhanging direction, the rotation and shear displacement are the main displacement composition in the positive and negative load, respectively. However, rotation displacement is always the main composition for the width direction Dou-Gong bracket in the positive and negative directions.

本文研究了平申科斗拱支架在悬伸和宽度方向下的抗震性能。义和堂两个全尺寸斗拱支架进行了拟静力试验。研究了加载方向对悬伸和宽度加载方向下整个模型的破坏模式、滞回特性、刚度和强度退化、能量耗散和变形能力的影响。此外，还讨论了斗拱支架组件的旋转和剪切位移。结果表明，当斗拱支架在悬伸和宽度方向加载时，大斗和馒头榫受到损伤。宽度方向承载的斗拱支架具有更高的承载能力，在悬伸方向下，初始刚度和能量耗散能力比斗拱支架差。然而，两个斗拱托槽的刚度和强度显着退化。构件的旋转和剪切位移随位移而增加。上部分量越高，旋转位移越大，但剪切位移不明显。斗拱支架在悬伸方向受力时，在正负载荷中，旋转位移和剪切位移分别是主要的位移组成。然而，旋转位移始终是宽度方向斗拱支架在正负方向上的主要组成部分。
