Features of base substantial differential settlements influence on structural system seismic stability
(Lira-K, 2016) Khokhlin, Denys
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. The article’s aim is to consider features of such influence. The considered spectrum of the influence aspects includes:initiation of a complex stress-strain state, which loads additionally structural system when seismic loads are emerging; reduction of the structural system energy capacity to take and absorb the seismic vibration energy; abatement and rupture of seismic stability elements in the construction system; substantial change of a dynamic analytical model. The version of soil base substantial differential settlements occurrence before earthquake is selected for being studied as the most probable and destructive. Design procedure for construction systems under combination of soil base substantial differential settlements influence and seismic action on the basis of capacity spectrum method proposed by author is shortly introduced.
