Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to an assembled conical special-shaped steel tube column base with a recoverable function and an assembling method.
Background
The steel frame structure is an effective anti-seismic system, and in order to realize better anti-seismic performance at relatively lower economic cost, the traditional structural steel structure is subjected to inelastic deformation under strong earthquake, and takes the prevention of collapse of the structural system under the action of the earthquake as a fundamental starting point. However, several times of earthquake disasters and researches at home and abroad in recent years show that after the traditional steel frame structure experiences strong earthquake, the structure can remain significant residual deformation, and the subsequent repair or dismantling-reconstruction work becomes a very serious challenge. With the sustainable development of urban construction in China, the distribution breadth and construction density of building steel structures are rapidly increased, and once a large number of building steel structures are destroyed under the action of earthquake, the consequences are not considered. Along with the development of society, the requirements of people on repairability, quick recovery and functional continuity of buildings after strong earthquake are continuously increased, so that the research and development of modern buildings with high earthquake resistance, less maintenance occupation time and low repair cost are promoted.
In order to realize the use function of a structure capable of being quickly restored after strong earthquake, a learner proposes a 'restorable function anti-seismic structure', namely a structure which can maintain acceptable functions when suffering from earthquake action, and can restore the use function without restoration after earthquake or with slight restoration in a partial use state. The method is characterized in that the structural system is easy to construct and maintain, and the whole service life is high in cost effectiveness. At present, the post-earthquake recoverable structure mainly comprises: 1. the structural system of the replaceable structural member (on the premise of reducing the influence on the using function of the structure, the replaceable and easy-to-replace structure is realized); 2. a structural system (changing the constraint form of the structure fixedly connected with the foundation) of a swinging wall or a swinging frame is arranged; 3. the self-healing architecture (eliminating residual deformation of the structural members due to yield energy consumption) is not completely independent and can sometimes be designed in a combination of two or even three ways.
The toe is the basic component of the earthquake-resistant steel frame, which affects the interlaminar displacement of the steel structure building, the forces in the structural components and the resistance to collapse. The recoverable column foot is used for separating the column from the foundation to form a gap under the action of an earthquake by releasing column foot constraint (setting a gap opening), and the damage after the earthquake is concentrated in the replaceable energy consumption device, so that the structural damage of the column is eliminated, and the restorability function of the structure is improved.
Therefore, there is a need to develop a high-efficiency energy-consuming column shoe structure with a recoverable function.
