关键词:轻钢龙骨外墙:钢框架:连接节点:静力性能:抗震性能 硕士研究生学位论文 Absract III Abstract Today steel frames infilled with sandwich posite panels have been widely used in steel residential houses then the connections between steel frames and panels have an important influcnce on the seismic behavior of this structure system.The connections are the key factor to ensure walls (panels) and stcel frames work together and resistance to damage its performance affects the stiffiess of structure system the stability and bearing capacity directly.If the connection failure in earthquakes sandwich posite panels will fall off morphology and lead to serious more disasters. There are very little researches on the connections between steel frames and panels in china so far Unified design standards have not formed because of the diversity of the connection. So the connection analysis has positive effects on the further development of the steel frames infilled with sandwich posite panel structural system in the industry.Inthis paper we will put forward anew kind connetionjoint oflight steel keel exterior wall and steel frame calculating the size refer to the specification. The seismic performance of the connection between steel frames and panels were studied through the cyclic loading test and monotonic loading test. This paper put forward a new kind connection joint of light steel keel exterior wall and steel frame. And construction measures for the new connecting node are illustrated. The feasibility of monotonic loading test kinds of exterior wall keel plate monly used in engineering are bined with connection joint in order to find the stress mechanism and failure mode. Under the horizontal low-cyclic loading we pare the skeleton curve of connection joint of light steel keel exteriorwall and steel frame.The main purpose is investigating the failure model and failure characteristic and analyzing the strength ductility and the energy dissipation. The experimental results show that these joints can provide very high shear strength and excellent quake-resist property.

It is consisted of intermal and external concrete wall board insulating layers and connectors ec. According to different material conneetor can be divided into three categories: mon reinforced connector alloy metal connector and fiber reinforced plastic ( FRP) connector. FRP connector has the property of low thermal conductivity good durability and high strength. Which can decrease the heat transfer coeficient of sandwich wall panel and has bright fore- ground in engineering applications. This paper introduces classification zesearch and application stand ards and specifications of FRP connector and offers the prospeet for research trend of FRP connector in future.
