Abstract: This paper reports the characterization of internal damping ratio (ξ) and Q factor of ultrahigh-performance fiber-reinforced concrete (UHPFRC) using acoustic tests for undamaged and damaged samples excited by an impact. ...

Abstract: This paper presents an advance in the analytical prediction of the contact interaction between bearing pads and precast beams. Contact problems are typically nonlinear, and until recently, there was no analytical proposition ...

Abstract: Precast prestressed concrete beams present camber after prestressing and early-age imperfections like initial sweep and rotations. Because there have been many reported cases of collapse with this type of element when ...
