Abstract: Underground reinforced concrete utility vaults play a vital role for the functioning of urban centers, providing space for all kinds of utility equipment. Underground structures are subjected to harsh environmental conditions ...

Abstract: This paper presents elements of seismic design for jointed precast cantilever wall units designed to rock about their foundation. Gravity loading and prestressed unbonded tendons provide the restoring force in these walls. ...

Abstract: This paper describes a displacement-based method of analysis for the performance-based seismic design of regular buildings with reinforced-concrete bearing walls acting as the lateral-force resisting system. The method ...

Abstract: Local calibration of the mechanistic-empirical pavement design guide (MEPDG) is performed by determining the pavement-performance model coefficients to minimize the difference between the measured and predicted distresses ...

Abstract: Precast segmental construction of bridges can accelerate construction and minimize the cost of medium span bridges in environmentally sensitive and difficult to access locations. Despite these benefits, the use of precast ...

Abstract: Recently issued seismic design guidelines for precast segment construction require nonlinear modeling of segment-to-segment joints of important bridges. The response of segment joints is highly dependent on the length of ...

Abstract: The beam-truss model (BTM), developed for the nonlinear cyclic analysis of reinforced concrete components including softening, is extended to compute the out-of-plane buckling observed in plastic hinges of various slender ...

Abstract: Stiffness modifiers are used in linear structural analysis programs to recognize the low-strain amplitude nonlinear material stress–strain response and support the design of reinforced concrete structures. For example, ...

Abstract: This paper describes a complete shear force–lateral displacement model for predicting the response envelope of shear-critical rectangular columns comprising (1) an effective stiffness, (2) nominal shear strength, ...
