【Abstract】 Taking reconstruction and expansion project of a middle school ’s brick-concrete structure buildings in a town in Hubei Province as an example,by means of solution designs as choosing the appropriate forms of structure,setting seismic joint suitably,using energy-conserving guarantee measure of the wall,selecting the strengthening method of the connections in new or old building and foundation treatment,we can guarantee that the project have better construction conditions and the old buildings still in work. In the meantime,the ability to resist earthquakes of the building would be improved,the requirements of structure stress would be contented,the cost of project would be reduced,and the great economic and environmental benefits would be achieved.更多还原
