The Study Of The Deformationg And Monitoring Of Ultra-long Base Isolated Structure Under The Temperature And Shrinkage

China is an earthquake-prone countries. The seismic great threat to people’s livesand property. In order to reduce the earthquake disaster, experts and scholars at homeand abroad did a lot of research work. One of the most direct and effective method isto base isolation. With the continuous development of China’s economic andtechnological base isolation technology is also used in practical. And improved inthe practical application. On the other hand, in order to meet the needs of the people,emerging some long plane size of buildings. So long base isolated structure has alsobecome the building structure a major trend.If the long isolation structure is divided into a number of structural units, eachunit isolated independently. In order to ensure that each unit in the earthquake doesnot occur to collide with each other the seismic seam between each unit is set toowide. Thus affecting the use of the structure. In order to solve such problems, duringisolation design, the structural unit can be placed in the same backplane and become amulti-tower with a large floor. Due to functional limitations, these buildings generallyrequire no or less set the temperature expansion joints. Tower seismic slit width valuein accordance with the ordinary earthquake structural requirements. The stiffness ofisolation layer is very small and Lack of restraint capacity. Temperature load, andshrinkage of concrete factors together, easy to make the isolation bearings have agreater relative deformation.In this paper combine a practical engineering problems. Establish the analyticalmodel with SAP2000finite element analysis software. Taking into account thecombined effect of temperature and shrinkage. Use the actual monitoring data.Analysis of the deformation modes of the structure. Studied the impact of structuraldeformation of practice and location of post-cast strip.Through analysis and research on the long isolated structure under the combinedeffect of temperature and shrinkage. Due to the stiffness of the isolation layer issmaller, lack of constraints on lateral deformation, and easily lead to largedeformation with should be controlled. The way of post-cast strip set will affect themaximum deformation of the structure.At the same time, in order to solve the trouble of long-term monitoring.Departure from the Internet of Things technology. Real-time upload of monitoringdata with Arduino+sensor. Reducing the monitoring cost.
