Study the Impact of Differential Settlement on Frame Structure through Back-Analysis Method

Abstract:

This paper studied the impact of differential settlement of foundation on the inner force of architectural structure by applying back-analysis method. By taking the three-dimensional coactions system of upper structure-piled raft foundation-foundation with different pile length and different raft thickness as the research object, its differential settlement law of foundation under the effect of load was studied, which was combined with the practical measured data to fit the quadratic settlement surface equation of the foundation. The analysis demonstrated that the differential settlement of foundation will change the inner force of upper structure significantly, thus enabling most of construction components to produce great additional axial force, additional shearing force and additional bending moment, especially changing the additional inner force of corner post more evidently.
