Earthquake Countermeasures For Rural Buildings In Village Of Hainan

In our country, most destructive earthquakes occurre in rural areas. Due to the economic backwardness of rural areas, villagers are serious lack of effective earthquake resistance measures. Rural buildings are falling down easily under earthquake action. The traditional seismic fortification measures is by increasing the strength of the material and structuring measures, which can not fundamentally solve the problem. Laminated rubber bearing has obvious seismic isolating effect, however, laminated rubber bearing is difficult to popularize in rural areas, due to the high cost, and complicated design procedure and construction technology.This paper presents two kinds of earthquake countermeasures,which according to rural buildings of Hainan. One is a new type isolation system, which is composed of graphite sliding device and simple rubber bearing, another is seismic measures with constructional column. Shaking table test for a typical brick masonry structure in village of Hainan is performed on a 1:4 scale. Theoretical analysis is also carried out. Results show that the proposed new isolation system can achieve a favorable level of performance. Give some suggestions about seismic resistance safety on rural buildings of Hainan.The main researches of this thesis are involved as follows:(1) Two kinds of earthquake countermeasures are presented ,which according to rural buildings of Hainan. One is a new type isolation system, which is composed of graphite sliding device and simple rubber bearing, another is seismic measures with constructional column. Shaking table test for a typical brick masonry structure in village of Hainan is performed on a 1:4 scale.(2) Carries on the correlation testing to the model material, examination mortar compressive strength and masonry compressive strength and shearing strength. A series of pressure-shear test is carried out for simple rubber bearing to examination the effective stiffness. A series of slip test is carried out for graphite sliding device to examination the friction coefficient.(3) Shaking table test is carried out for original structure model. Simulation analysis of reinforced structure model is implemented using ETABS. Based on this, dynamic analysis is given.(4) Shaking table test is carried out for reinforced structure model. Simulation analysis of reinforced structure model is implemented using ETABS. The results show that , reinforced structure can delay the occurrence of crack.(5) Shaking table test is carried out for the new type isolated structure model. Simulation analysis of the new type isolated structure model is implemented using ETABS. The results show that, the new type isolated structure has good damping effect.
