Bending Resistance Capacity of Steel Pile Caps Strengthened with Perfobond Shear Connectors
Keywords:steel pipe pile, perfobond shear connector, concrete foundation, bending resistance
This study proposes a new perfobond shear connector, which can be used to strengthen the steel pile cap embedded into the structural foundation. The bending resistance capacity of the steel pile cap strengthened with the proposed perfobond connectors is evaluated by performing a test on seven specimens. Test parameters include the type of perfobond shear connectors, infilled concrete depths and number of L-shaped steel plates. The lateral load versus displacement curve is plotted for all specimens, and their failure modes are identified. The effects of the test parameters on the bending resistance capacity of the specimen are examined in this work.
