Building protection in conditions of simultaneous availability of soil base substantial differential settlements and seismic hazard origins

Abstract

The problem of possible combination of soil base substantial differential settlements and seismic action is characterized. This theme is extremely urgent subject to significant negative influence of soil base substantial differential settlements evolution on the construction system seismic stability and also to possibility of continuation of base settlements after earthquake. The article’s aim is to consider of building protection features in conditions of both complex influence simultaneous availability. Sequence of theme uncovering in the article consists of the building protection strategy selection in conditions under consideration; straight consideration of recommended protection measures; approaches to the calculation analysis of developed measures. Differentiation of building protection strategies and approaches to the calculation analysis is occurred on basis of the building responsibility class CC-1, CC-2, CC-3 and possible consequences and costs from damages and collapse of buildings. Approaches for building protection methods from separate influences of base settlements or seismic and also results of pre-existing investigations of such influences combination features are analyzed for separation of proposed possible protection measures complex.
