Lateral Dynamic Bridge Deck–pier Interaction for Ultra-High-speed Hyperloop Train loading
Author(s) Ehsan Ahmadi, PhD Nicholas A. Alexander, PhD Mohammad M. Kashani, PhD Abstract The next generation of ultra-high-speed (UHS) trains, known as Hyperloop and TransPod, are aerospace type vehicles designed to carry passengers. The UHS employs a vehicle...
Evaluation of In-Place Stress in Concrete by Incremental Hole Drilling
Author(s) Ashutosh G. Dabli, Abhay N. Bambole, and Kamalkishor M. Bajoria Abstract The use of strain relief method is one of the most direct methods for determination of in-place stresses. In this method, a hole is drilled in the concrete member and the change...
Insights into the Transport and Fragmentation Characteristics of Earthquake-Induced Rock Avalanche: Numerical Study
Aouthor(s) Ge Gao ; Mohamed A. Meguid, Ph.D., M.ASCE ; Luc E. Chouinard, Sc.D. ; and Chong Xu, Ph.D Abstract The earthquake-induced rock avalanche in the Tangjia Valley was the most notable geological disaster triggered by the Lushan earthquake in 2013. In...
Finite-Element Study for Seismic Structural and Global Stability of Cantilever-Type Retaining Walls
Aouthor(s) Junied Bakr; Syed Mohd Ahmad; and omenico Lombardi Abstract This paper investigates the structural and global stability of a cantilever-type retaining wall under seismic loading using numerical modelling. A new and robust approach is proposed to...
Yao Li, S.M.ASCE; Yunming Yang; Hai-Sui Yu, M.ASCE; and Gethin Roberts
Aouthor(s) Yao Li, S.M.ASCE; Yunming Yang; Hai-Sui Yu, M.ASCE; and Gethin Roberts Abstract Stress–strain responses of Leighton Buzzard sand are investigated under bidirectional shear. The tests are conducted by using the variable direction dynamic cyclic simple...
Structural Analysis for Shallow Tunnels in Soft Soils
Aouthor(s) Minh Ngan Vu; Wout Broere; and Johan W. Bosch Abstract Generally, studies on structural design for bored tunnels focus on moderate to deep tunnels (cover-to-diameter ratio C/D ≥ 2). Such tunnel design methods cannot be used for shallow-situated bored...
Low-Velocity Impact Load Testing of RC Beams Strengthened in Flexure with Bonded FRP Sheets
Aouthor(s) Norimitsu Kishi, Ph.D., M.ASCE ; Masato Komuro, Ph.D. ; Tomoki Kawarai ; and Hiroshi Mikami, Ph.D Abstract In this paper, which focuses on the fiber-reinforced polymer (FRP) sheet bonding method for improving the impact resistance of RC beams,...
Optimization of Fiber-Reinforced Polymer Patches for Repairing Fatigue Cracks in Steel Plates Using a Genetic Algorithm
Auothor(s) Bach Do and Akhrawat Lenwari Abstract A practical design optimization of fiber-reinforced polymer (FRP) patches for repairing fatigue cracks in metallic structures is presented. The design procedure combines finite-element (FE), genetic programming...
Flexural Strengthening of Two-Way RC Slabs with Textile-Reinforced Mortar: Experimental Investigation and Design Equations
Aouthor(s) Lampros N.Koutas, Ph.D., Aff.M.ASCE; and Dionysios. A.Bournas, Ph.D Abstract The application of textile-reinforced mortar (TRM) as a means of increasing the flexural capacity of two-way reinforced concrete (RC) slabs is experimentally investigated in...
