In order to withstand challenges such as earthquakes, it is important to appropriately design the beam-to-column connection of precast structures. Numerous precast connections were designed to be used worldwide to attain satisfactory seismic performance. The failures observed for many beam–column connections were primarily due to the brittle behaviour of poor connection details between the precast concrete members. This review article examines past experimental studies which used hybrid precast connections comprised of three types: (1) dry and wet connections with steel sections (Type I), (2) composite concrete (Type II), and (3) composite concrete and steel sections (Type III). The seismic performance behaviour of these connection types was evaluated and compared with that of the monolithic connections. The analysis showed that both the dry semi-rigid and rigid connections Type I can be implemented in the seismic zones. In addition, most of the wet connections Type I, Type II, and Type III can simulate the behaviour of monolithic rigid connections. Therefore, the wet connections Type I, Type II, and Type III can withstand high seismic excitations. Overall, the performance of hybrid dry connection Type I can be improved by using strengthening technique methods in the connection to maintain the continuity of the PC beam. Moreover, the use of composite materials with and without the steel sections as connector elements in the connection (Type II and Type III) can be a feasible method to simulate the seismic performance of monolithic connections.

混合预制梁柱连接的抗震性能行为综述

为了抵御地震等挑战,适当设计预制结构的梁柱连接非常重要。许多预制连接被设计用于在全球范围内使用,以获得令人满意的抗震性能。对于许多梁柱连接观察到的失效主要是由于预制混凝土构件之间不良连接细节的脆性行为。这篇评论文章检查了过去使用由三种类型组成的混合预制连接的实验研究:(1) 干式和湿式钢截面连接(I 型),(2) 复合混凝土(II 型),以及 (3) 复合混凝土和钢部分(类型 III)。对这些连接类型的抗震性能行为进行了评估,并与整体连接进行了比较。分析表明,干式半刚性连接和Ⅰ型刚性连接均可在地震区实施。此外,大多数 I 型、II 型和 III 型湿连接都可以模拟整体刚性连接的行为。因此,I 型、II 型和 III 型湿连接可以承受高地震激发。总的来说,通过在连接中使用加强技术方法来保持PC梁的连续性,可以提高I型混合干式连接的性能。此外,在连接(II 型和 III 型)中使用带和不带钢截面的复合材料作为连接器元件可以成为模拟整体连接抗震性能的可行方法。大多数湿连接类型 I、类型 II 和类型 III 可以模拟整体刚性连接的行为。因此,I 型、II 型和 III 型湿连接可以承受高地震激发。总的来说,通过在连接中使用加强技术方法来保持PC梁的连续性,可以提高I型混合干式连接的性能。此外,在连接(II 型和 III 型)中使用带和不带钢截面的复合材料作为连接器元件可以成为模拟整体连接抗震性能的可行方法。大多数湿连接类型 I、类型 II 和类型 III 可以模拟整体刚性连接的行为。因此,I 型、II 型和 III 型湿连接可以承受高地震激发。总的来说,通过在连接中使用加强技术方法来保持PC梁的连续性,可以提高I型混合干式连接的性能。此外,在连接(II 型和 III 型)中使用带和不带钢截面的复合材料作为连接器元件可以成为模拟整体连接抗震性能的可行方法。通过在连接中采用加强技术方法保持PC梁的连续性,可以提高I型混合干式连接的性能。此外,在连接(II 型和 III 型)中使用带和不带钢截面的复合材料作为连接器元件可以成为模拟整体连接抗震性能的可行方法。通过在连接中采用加强技术方法保持PC梁的连续性,可以提高I型混合干式连接的性能。此外,在连接(II 型和 III 型)中使用带和不带钢截面的复合材料作为连接器元件可以成为模拟整体连接抗震性能的可行方法。
