Steel pipe piles supporting buildings may lose lateral resistance during strong earthquakes because local buckling at pile heads degrades member strength under high axial force. Although the lateral resistance of single piles and pile groups has been widely studied, a rational framework for evaluating the ultimate lateral resistance of superstructure–pile foundation–soil systems while accounting …

The influence line for a point on a structure shows how shear force or bending moment, or typical strain components, at that point changes as a unit load moves along the structure. The bridge influence line can be used in Bridge Weigh-in-Motion (BWIM) systems and Structural Health Monitoring (SHM) systems. Influence line identification from measurement data is a possible alternative to Finite Ele…
