RISPre-Liquefaction and Post-Liquefaction Responses of Axially Loaded Piles in Sands
Publisher: American Society of Civil Engineers
Abstract: This paper presents a methodology for predicting the mobilized response of axially loaded piles in sands in the states of pre-liquefaction and post-liquefaction. The proposed procedure calculates shaft and skin resistance ...
Contribution of Vertical Skin Friction to the Lateral Resistance of Large-Diameter Shafts
Publisher: American Society of Civil Engineers
Abstract: Large-diameter drilled shafts embedded in stiff materials (e.g., clay and weak rock) experience larger lateral resistance compared to the resistance values obtained from available soil-pile models, which usually produce a ...
Effect of Buried and Watercourse-Crossing Pipeline Vibrations on Canal Bed Stability
Publisher: ASCE
Abstract: Pipe jacking, microtunneling, and pipe ramming are common trenchless techniques for installing pipelines or cables below the bed of watercourses. A tunnel boring machine (TBM) is also used for constructing pipelines with ...
Seismic Strengthening of Severely Damaged Beam-Column RC Joints Using CFRP
Publisher: American Society of Civil Engineers
Abstract: This article investigates the seismic behavior of three full-scale exterior reinforced concrete (RC) beam-column joints rehabilitated and strengthened with externally bonded carbon fiber–reinforced polymers (CFRP). The ...
Numerical Assessment of the Performance of Bed Water Jets in Submerged Hydraulic Jumps
Publisher: ASCE
Abstract: Submerged hydraulic jumps commonly occur downstream of irrigation structures. Submerged hydraulic jumps dissipate energy to some extent, and bed water jets can be employed as a means to increase their energy dissipation. ...
Effect of Floating Bridges on Open Channels’ Flow and Bed Morphology
Publisher: American Society of Civil Engineers
Abstract: Floating bridges are permanent or temporary bridges supported by pontoons. This research was initiated to experimentally study the effect of floating bridges on flow characteristics and bed morphology. Two hundred and ...
Effect of Short- and Long-Term Aging on the Rheological and Chemical Properties of Asphalt Binders Modified with Different Technologies
Publisher: ASCE
Abstract: This research aims to investigate the impact of short- and long-term aging on the chemo-physical properties of various conventional and modified asphalt binders. The study incorporates different technologies, namely, ...
Estimating the Thermal Radiative Properties of Shading Nets Under Natural Outdoor Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The perforated nature of nets makes it impossible to measure the thermal radiative properties (emittance, εn, transmittance, τn, and reflectance, ρn) correctly by using any measuring device under natural conditions. In ...
Nanomodified Asphalt Binders Aging Study and Predicted Performance under Different Climatic Conditions Using AASHTOWare
Publisher: American Society of Civil Engineers
Abstract: Nanomaterials have shown great potential in improving the mechanical and rheological properties of asphalt binders based on laboratory examination. Some nanomaterials were reported to improve asphalt binders’ resistance ...
Semi-Transparent Photovoltaic Thermal Greenhouse System Combined With Earth Air Heat Exchanger for Hot Climatic Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Semi-transparent photovoltaic thermal (SPVT) greenhouse system combined with an earth air heat exchanger (EAHE) has been developed to make the system sustainable. The system is designed to cultivate plants in a hot climatic ...
