RISResearch on Cracking of Reinforced Concrete Beam and Its Influence on Natural Frequency by Expanded Distinct Element Method
Publisher: American Society of Civil Engineers
Abstract: A distinct element model was proposed to simulate cracking in a reinforced concrete beam, and the influence of cracking on natural frequency was analyzed. Hexagonal block and tensile-shear failure criteria were implanted ...
Experimental Research on the Structural Performance of Shield Tunnel Segments Subjected to Different Fire Temperatures
Publisher: American Society of Civil Engineers
Abstract: In order to determine the damaging effect of different fire temperatures on a segment, experimental research was carried out on the structural performance of segments subjected to different fire temperatures. A temperature ...
Effects of Bolt Anchoring on Shear Mechanical Performance and Acoustic Emission Characteristics in Two Parallel Coplanar Rock-Like Materials
Publisher: American Society of Civil Engineers
Abstract: Rock slope landslides and underground construction destabilization are frequently attributed to shear impairment by intermittent joints, and the support by bolts represents an indispensable technique for reinforcing jointed ...
