RISUsing Inclinometers to Measure Bridge Deflection
Publisher: American Society of Civil Engineers
Abstract: Deflection of a bridge span under designed loads is an important parameter for bridge safety evaluation. However, it is inconvenient to obtain the bridge deflections directly. For bridges over rivers, railways, or highways, ...
Experimental Study on the Influence of Size Effects on Compressive Dynamic Behavior of Lightweight Concrete
Publisher: ASCE
Abstract: To study the impact of the strain rate effect and size effect on the compressive dynamic behavior of lightweight concrete (LC), 3 cube sizes and 10 strain rates were set up, and uniaxial compression tests were conducted ...
Real-Time Dynamic Warning on Deflection Abnormity of Cable-Stayed Bridges Considering Operational Environment Variations
Publisher: ASCE
Abstract: Long-span bridges face various threats every day due to their sophisticated operational environments. To investigate the operational state of bridges, a real-time dynamic warning method on the abnormity of cable-stayed ...
Experimental Study on Dynamic Performance of Plain Concrete and Lightweight Aggregate Concrete under Uniaxial Loading
Publisher: ASCE
Abstract: To examine the uniaxial behaviors of plain concrete and lightweight aggregate concrete under dynamic loadings, the plain concrete specimens and lightweight aggregate concrete specimens prepared by shale ceramsite were ...
Site-Specific Extreme Load Estimation of a Long-Span Cable-Stayed Bridge
Publisher: ASCE
Abstract: To provide benefit for design, rating, evaluation and management of signature bridges, site-specific extreme wind speeds, structural temperatures, and traffic load effects of a long-span cable-stayed bridge were estimated ...
Experimental Study on Mechanical Properties and Failure Criteria of Self-Compacting Concrete under Biaxial Tension-Compression
Publisher: American Society of Civil Engineers
Abstract: In order to explore the basic mechanical properties of self-compacting concrete, ordinary concrete, lightweight aggregate concrete, self-compacting ordinary concrete, and self-compacting lightweight aggregate concrete were ...
Failure Criteria and Mechanical Properties of Recycled Concrete with Different Replacement Ratios of Coarse Aggregates under Multiaxial Compression
Publisher: American Society of Civil Engineers
Abstract: In this paper, experiments of recycled aggregate concrete under multiaxial compression with five different replacement ratios (0%, 25%, 50%, 75%, and 100%) of coarse aggregates were implemented by using the true triaxial ...
Experimental Study on Mechanical Properties and Failure Criteria of Self-Compacting Concrete under Biaxial Tension-Compression
Publisher: American Society of Civil Engineers
Abstract: In order to explore the basic mechanical properties of self-compacting concrete, ordinary concrete, lightweight aggregate concrete, self-compacting ordinary concrete, and self-compacting lightweight aggregate concrete were ...
Coupled CFD–FEM Simulation Methodology for Fire-Exposed Bridges
Publisher: ASCE
Abstract: Evaluating the fire performance of bridges is necessary for damage mitigation as more fire-related accidents occurred on bridge structures. Current solutions adopting temperature curves can result in significant inaccuracy ...
Experimental Study and Mechanism Analysis of the Dynamic Performance of Plain Concrete under Combined Compression and Shear
Publisher: American Society of Civil Engineers
Abstract: Concrete is obviously affected by the loading strain rate, and concrete exists in the state of shear multiaxial stress in practical engineering. Studying the dynamic response of concrete under multiaxial shear states ...
