Strut-and-Tie Modeling and Design of Drilled Shaft Footings: Biaxial Load Combinations

Design recommendations developed during the course of TxDOT Project 0-6953 provided much needed guidance when establishing three-dimensional strut-and-tie models for the design of drilled shaft supported footings. The research team will expand on the original five load cases examined in 0-6953 and develop strut-and-tie models for two additional biaxial load cases which are very common in everyday design and bridge construction and for which no STM guidance is explicitly provided. Development of strut-and-tie models for the additional biaxial cases shall provide much needed insight when implementing STM in design for complex load scenarios and will significantly enhance the confidence when using the STM provisions.
