Abstract: By in situ measurements, the real distribution of stress ranges caused by service loads can be recorded. Inherent effects in the measured response as disturbance can, however, create puzzles in the interpretation of the ...

Abstract: This paper investigates the fatigue assessment of existing steel bridges. Measurements can be used to reduce uncertainties in the structural behavior and the effects of action. However, the treatment of the measured response ...

Abstract: Life-cycle cost analysis (LCCA) has recognized potential for rationalizing bridge procurement, but its use in this context is far from systematic. The integration of LCCA findings in decisions is often far from robust. ...

Abstract: Cash flow impacts all aspects of the construction project implementation process. Cash shortages can lead to project failure and business bankruptcy. Researchers have studied cash flow in the context of scheduling, project ...

Abstract: As ultra-high-performance concrete (UHPC) becomes more widely used, the need for good concrete tensile tests for fiber-reinforced concrete has become apparent. However, there is not yet one universally used test method. ...

Abstract: The integration of large infrastructure with energy-harvesting systems is a growing field with potentially new and important applications. The possibility of energy harvesting from ambient vibration of bridges is a new ...

Abstract: AbstractDirect tension tests were conducted on fiber-reinforced concretes with strengths ranging from high-strength to ultrahigh-performance concrete (UHPC) (83–165 MPa or 12–24 ksi) to determine how mixture ...

Abstract: Physical salt attack (PSA) or salt weathering occurs as a result of the crystallization pressures in concrete pores exerted by phase changes of salts that penetrate the concrete. The crystallization pressures cause ...
