Capacity design, according to the modern seismic building codes, requires the application of specific rules and construction details in order to prevent brittle failure modes at material, element and structural level. In particular, with reference to single-story precast reinforced concrete structures with columns joined by pinned beams, the Italian seismic building code, following the Eurocode 8 general principles, requires that beam-to-column connection should be designed in order to avoid the connection failure before the formation of the plastic hinge at the column base. However, no specific details are provided in order to reach such a performance. Recent European earthquakes showed that seismic performance of beam-to-column dowel connections can be very poor. Hence, for European typical dowel beam-to-column connections, this study aims to investigate: (a) possible connection configurations obtained according to seismic design; (b) possible failure modes involving connection elements (steel dowel, transversal steel reinforcement, dowel concrete cover); (c) how available formulations are able to describe such failure modes and the related shear strength; (d) influence of connection failure on the global seismic safety at collapse of new designed single-story RC precast buildings. The reference buildings and beam-to-column connections are designed considering different geometrical layouts of the primary structure and different seismic hazard levels, i.e. four sites and two soil types. Structural capacity is estimated considering global, i.e. related to column plastic hinge degradation measured in terms of top lateral displacements, and local, i.e. related to connection shear strength, failure modes. Nonlinear multi-stripe analyses are performed for the seismic assessment.

根据现代抗震建筑规范，容量设计需要应用特定的规则和构造细节，以防止在材料，元素和结构级别出现脆性破坏模式。尤其是，对于柱通过钉梁连接的单层预制钢筋混凝土结构，意大利的地震建筑规范遵循欧洲规范8的一般原则，要求设计横梁至柱的连接以避免连接在柱底形成塑料铰链之前发生故障。但是，没有提供具体细节以达到这种性能。最近的欧洲地震表明，梁柱销的连接抗震性能可能很差。因此，对于欧洲典型的销钉梁到柱连接，本研究旨在调查：（a）根据抗震设计获得的可能的连接配置；（b）涉及连接元件（钢榫，横向钢筋，榫混凝土盖）的可能的失效模式；（c）现有的配方如何描述这种破坏模式和相关的剪切强度；（d）新设计的单层RC预制建筑物倒塌时连接故障对全球地震安全的影响。参考建筑物和梁柱连接的设计考虑了主要结构的不同几何布局和不同的地震危险等级，即四个地点和两种土壤类型。估计结构能力时要考虑整体因素，即与根据顶部横向位移测量的圆柱塑性铰的退化有关，而局部因素即 与连接抗剪强度，破坏模式有关。进行非线性多条带分析以进行地震评估。
