Abstract: The selection and evaluation of finite-element modeling approaches for predicting cyclic behavior of structural concrete is presented. Nonlinear material models for structural concrete are evaluated through comparison of ...

Abstract: A new seismic retrofit technique for unreinforced masonry infills in nonductile reinforced concrete frames is presented. The objective was to develop a light and easy to apply retrofit technique for the infills that both ...

Abstract: This paper focuses on improving the efficiency and aesthetics of standard highway bridges with attention to cast-in-place substructure design. Standard short- and moderate-span bridges are predominantly functional and ...

Abstract: A precast segmental concrete bridge pier system is being investigated for use in seismic regions. The proposed system uses unbonded posttensioning (UBPT) to join the precast segments and has the option of using a ductile ...

Abstract: A two-dimensional non-linear finite-element analysis micro-modeling approach to simulate unreinforced masonry beams in bending is extended to include a retrofit with a thin layer of ductile fiber-reinforced cement-based ...

Abstract: This paper focuses on improving bridge substructures by developing attractive and rapidly constructed substructure systems for short- and moderate-span bridges. The importance of improved substructure design is discussed. ...
