ABSTRACT

In timber structures, connections traditionally provide ductility and energy dissipation under seismic loading. Capacity design ensures that the global structural response is ductile by applying overstrength to the design demand of brittle elements. Overstrength is often derived experimentally which is costly and time-consuming. This paper proposes an analytical method to estimate the overstrength of dowel-type timber connections based on inherent material properties, thereby reducing the need for experimental testing. The method is validated with data from previous experiments and literature for dowelled, bolted, and nailed timber connections, and provides reasonably accurate upper-bound overstrength estimates.

摘要

在木结构中，连接传统上在地震载荷下提供延展性和能量耗散。容量设计通过将超强度应用于脆性元件的设计需求，确保整体结构响应具有延展性。超强度通常是通过实验得出的，这既昂贵又耗时。本文提出了一种分析方法，根据固有的材料特性来估计销式木材连接的超强度，从而减少了对实验测试的需要。该方法使用来自先前实验的数据和有关木榫、螺栓和钉钉的木材连接的文献进行了验证，并提供了合理准确的上限超强度估计值。
