本文件涉及单层或多层建筑的预制框架系统中的连接。考虑了所有接头顺序的连接。不考虑大型墙板和三维单元系统。 根据在整体结构中的位置和随之而来的不同结构功能，考虑以下七种接头顺序: a)在结构系统的抗震性能中，与楼板的横隔板作用有关的楼板或屋顶元件（楼层对楼层）之间的相互接缝； b)楼板或屋顶元件与支撑梁(楼板到梁)之间的接头，其对楼板隔板的抗震性能给予外围约束； c)梁和柱(梁到柱)之间的接头，其在任何方向上确保框架系统中所需的约束程度；d)用于通常用于双壁支撑系统的多层建筑的柱段(柱对柱)之间的接头； e)柱与基础(柱与基础)之间的接头，能够确保柱在任何平面内的固定完全支撑； f)将覆层面板紧固到结构上(面板到结构)，以确保面板在地震作用下预期的高作用力或大漂移下的稳定性； g)可能用于增加周边壁系统的刚度并提供额外的能量耗散源的相邻覆层板(板对板)之间的接头。 不考虑通过重力载荷摩擦工作的简单轴承。滑动和弹性变形支撑装置都不是，所有这些类型的连接都不适合传递地震作用。 该文件提供了大量接头类型的强度设计公式。

This document refers to connections in precast frame systems, either for single-storey or multi-storey buildings. The connections for all orders of joints are considered. Large wall panel and three-dimensional cell systems are not considered. According to the position in the overall construction and of the consequent different structural functions, the seven following orders of joints are considered: a) mutual joints between floor or roof elements (floor-to-floor) that, in the seismic behaviour of the structural system, concern the diaphragm action of the floor; b) joints between floor or roof elements and supporting beams (floor-to-beam) that give the peripheral constraints to the floor diaphragm in its seismic behaviour; c) joints between beam and column (beam-to-column) that ensure in any direction the required degree of restraint in the frame system; d) joints between column segments (column-to-column) used for multi-storey buildings usually for dual wall braced systems; e) joints between column and foundation (column-to-foundation), able to ensure in any plane a fixed full support of the column; f) fastenings of cladding panels to the structure (panel-to-structure) that ensure the stability of the panels under the high forces or the large drifts expected under seismic action; g) joints between adjacent cladding panels (panel-to-panel) possibly used to increase the stiffness of the peripheral wall system and provide an additional source of energy dissipation. Simple bearings working by gravity load friction are not considered. Sliding and elastic deformable supporting devices neither, being all these types of connections not suitable for the transmission of seismic actions. The document provides formulae for the strength design of a large number of joint typologies.
