Abstract The concept of post-tensioned rocking structures was successfully applied to timber in 2005, in prestressed laminated timber (Pres-Lam) technology. When applied to moment-resisting frames, the technology relies on unbonded post-tensioning tendons passing through hollow beams and the supporting column to provide beam–column connections with moment capacity. Supplemental dissipation devices can be included in the design, resulting in a recentring/dissipative system. Since seismic movements are accommodated through a control rocking mechanism between the beam and the column, the detailing of the beam–column joint can significantly affect the seismic performance of the structure. Among the main concerns, the shear transfer system should be able to transfer shear forces without interfering with the rocking motion, and ignoring the face friction and joint deformation should not compromise the drift activation of the gap opening. Attention should also be paid to minimizing post-tensioning losses while providing access for potential retensioning. As a result of the continuous and rapid development of Pres-Lam frame systems, a wide range of alternative solutions for connection detailing has been tested in the laboratory or implemented in existing buildings. This paper presents an overview of the beam–column detailing implemented in the five Pres-Lam frame buildings currently operative in New Zealand.

后张式耗散木框架的连接详图概述

摘要 后张摇摆结构的概念于2005年在预应力层压木材（Pres-Lam）技术中成功应用于木材。当应用于抗弯框架时，该技术依赖于穿过空心梁和支撑柱的无粘结后张预应力筋，以提供具有抗弯能力的梁柱连接。设计中可以包含补充耗散设备，从而形成重心/耗散系统。由于地震运动是通过梁和柱之间的控制摇摆机制来调节的，因此梁柱接头的细节会显着影响结构的抗震性能。在主要问题中，剪切传递系统应该能够在不干扰摇摆运动的情况下传递剪切力，忽略面摩擦和接头变形不应影响间隙开口的漂移激活。还应注意尽量减少张拉后损失，同时为潜在的再张拉提供通道。由于 Pres-Lam 框架系统的持续快速发展，已经在实验室测试或在现有建筑物中实施了广泛的连接详图替代解决方案。本文概述了目前在新西兰运营的五座 Pres-Lam 框架建筑中实施的梁柱详图。由于 Pres-Lam 框架系统的持续快速发展，已经在实验室测试或在现有建筑物中实施了广泛的连接细部替代解决方案。本文概述了目前在新西兰运营的五座 Pres-Lam 框架建筑中实施的梁柱详图。由于 Pres-Lam 框架系统的持续快速发展，已经在实验室测试或在现有建筑物中实施了广泛的连接详图替代解决方案。本文概述了目前在新西兰运营的五座 Pres-Lam 框架建筑中实施的梁柱详图。
