Analysis and design of hammerhead bridge pier using a strut and tie method

The main advantages of truss model are their transparency and adaptability to arbitrary geometric and loading configuration. In strut-and-tie modeling, the internal stresses are transferred through a truss mechanism. The tensile ties and compressive struts serve as truss members connected by nodal z...

description The main advantages of truss model are their transparency and adaptability to arbitrary geometric and loading configuration. In strut-and-tie modeling, the internal stresses are transferred through a truss mechanism. The tensile ties and compressive struts serve as truss members connected by nodal zones.
