Core column type double-flange self-resetting beam-column connecting joint structure
The embodiment of the invention provides a core column type double-flange self-resetting beam-column connecting joint structure. The core column type double-flange self-resetting beam-column connecting joint structure comprises an upper steel column, a core column base, a lower steel column, a steel beam and a steel beam short beam section, wherein the upper steel column, the core column base, the lower steel column, the steel beam and the steel beam short beam section are all prefabricated parts; the core column base is located between the upper steel column and the lower steel column, the upper steel column and the core column base are connected through a flange plate, and the lower steel column and the core column base are connected through a flange plate; and one end of the steel beam short beam section is connected with the core column base through a web connecting assembly, and the other end of the steel beam short beam section is connected with the steel beam through a damper and a prestressed steel strand. According to the core column type double-flange self-resetting beam-column connecting joint structure, in an assembly type steel structure, high-strength bolt connection is adopted to replace common welding, so that welding-free full assembly on a construction site is realized; and pre-tension is applied to the prestressed steel strand, so that the functions of bearing before an earthquake, opening energy consumption in the earthquake and resetting after the earthquake are realized.
本发明实施例提供了一种芯柱式双法兰自复位梁柱连接节点构造，包括：上钢柱、芯柱柱座、下钢柱、钢梁和钢梁短梁段，上钢柱、芯柱柱座、下钢柱、钢梁和钢梁短梁段均为预制构件；芯柱柱座位于上钢柱和下钢柱之间，上钢柱与芯柱柱座、下钢柱与芯柱柱座间均通过法兰板进行连接；钢梁短梁段一端与芯柱柱座通过腹板连接组件进行连接，钢梁短梁段另一端与钢梁通过阻尼器以及预应力钢绞线进行连接。本发明实施例提供了一种芯柱式双法兰自复位梁柱连接节点构造，在装配式钢结构中，采用高强度螺栓连接代替普通焊接，实现施工现场无焊接全装配，通过对预应力钢绞线施加预拉力，实现地震前承重，地震中开口耗能，地震后复位的功能。
