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...
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...
Strengthening of Concrete Structures with Textile Reinforced Mortars: State-of-the-Art Review
Aouthor(s) Lampros N. Koutas; Zoi Tetta; Dionysios A. Bournas; and Thanasis C. Triantafillou, P.E., M.ASCE Abstract Textile reinforced mortars (TRM), also known in the international literature as textile reinforced concrete (TRC) or fabric reinforced...
Remote Bridge Monitoring Using Infrasound
Aouthor(s) R. Danielle Whitlow, P.E.; Richard Haskins; Sarah L. McComas; C. Kennan Crane, Ph.D., Abstract As transportation infrastructure continues to age, new methods of noncontact sensing should be evaluated and, if found suitable, used for bridge monitoring...
Pedestrian-Induced Vibrations of Footbridges: An Extended Spectral Approach
Author(s) K. Van Nimmen ; P. Van den Broeck ; G. Lombaert ; and F. Tubino Abstract The vibration serviceability assessment of footbridges under pedestrian traffic requires a probabilistic approach considering the uncertainty in the dynamic behavior of the...
