Novel assembly type cold-formed steel frame-X-shaped supporting structure
The invention provides a novel assembly type cold-formed steel frame-X-shaped supporting structure. An X-shaped support provided with an energy consumption section in the structure is composed of four I-shaped cold-formed section steel supports and the energy consumption section. The energy consumption section is composed of an energy consumption plate and annular stiffening ribs welded to the periphery of the energy consumption plate. Under the action of earthquake load, the energy dissipation section with low yield strength enters plastic energy dissipation earlier than the beams, the columns and other components, large plastic deformation of the beams, the columns and other components is avoided while the energy dissipation capacity of the structure is improved, and the recoverability of the structure is improved. All the components in the structure can be used, dismantled and recycled, construction procedures such as welding are omitted on site, the structure has the advantages of being short in construction period, good in durability, sustainable and the like, and housing industrialization and prefabrication are facilitated.
发明提供一种新型装配式冷弯型钢框架—X形支撑结构。该结构内部的配置耗能区段的X形支撑，由4根工字形冷弯型钢支撑与耗能区段组成。耗能区段由耗能板以及在四周焊接的环形加劲肋组成。在地震荷载作用下，具有较低屈服强度的耗能区段先于梁、柱等构件进入塑性耗能，在提高结构耗能能力的同时避免梁、柱等构件发生较大塑性变形，提高结构的可恢复性。该结构中的所有构件可实现使用、拆除与回收的循环利用，现场无焊接等施工工序，具有施工周期短、耐久性好及可持续等优点，有利于住宅产业化、预制装配化。
