Nonlinear Finite-Element Analysis of Glass Fiber- Reinforced Polymer-Reinforced Concrete Slab-Column Edge Connections
Author(s) Ahmed E. Salama, Mohamed Hassan, and Brahim Benmokrane Abstract Because of the limited experimental evidence on slab-column edge connections reinforced with fiber-reinforced polymer (FRP) bars, the FRP design codes call for further experiments to...
Effectiveness of Hybrid Fibers on Flexural Behavior of Concrete Beams Reinforced with Glass Fiber-Reinforced Polymer Bars
Author(s) Ganapati M. Patil, M. Chellapandian, and S. Suriya Prakash Abstract The effectiveness of structural macro-synthetic polyolefin (PO) and a hybrid combination of steel and synthetic fibers on the flexural performance of glass fiber-reinforced polymer...
Cracking Behavior of Slabs with Corrosion-Resistant and High-Strength Reinforcing Bars
Author(s) Chungwook Sim and Robert J. Frosch Abstract Crack control remains important even if corrosion-resistant reinforcement (chromium-containing or -chromium-coated bars) is used because cracking of the concrete can lead to durability concerns such as...
Shear Behavior of Lightweight Slag Aggregate Self- Consolidating Concrete Beams
Author(s) Khandaker M. Anwar Hossain, Kokilan Sathiyamoorthy, Tanvir Manzur, and Abdurrahmaan Lotfy Abstract Lightweight self-consolidating concrete (LWSCC) has evolved to combine the excellent benefits of self-consolidating concrete (SCC) and lightweight...
Experimental Study of Direct Shear in Concrete with Recycled Aggregate
Author(s) Juliana Trindade, Sergio Garcia, and Gabriel Fonseca Abstract To investigate shear transfer in recycled and natural coarse aggregate concrete, 45 pushoff specimens were tested. Replacement levels of natural coarse aggregates by recycled aggregates in...
Alex Lehnerer’s Rühlstrasse House Introduces Curving Concrete to Bavaria
Architect alex lehnerer has completed the ‘rühlstrasse house’ at the edge of a bavarian forest, realized with sculpturally cast concrete. the surrounding context is characterized by typical 1960s-era bungalow style dwellings in which program is consolidated entirely...
Liquefied Strength and Its Relationship to Effective Stress
Authour(s) Robb Eric S. Moss, Ph.D., P.E., F.ASCE Abstract The residual strength of liquefied soil (su,r) is a large-strain strength variable often used for forecasting the seismic stability of dams, embankments, and mine tailings. This variable is usually...
Numerical Simulation of the Effect of High Confining Pressure on Drainage Behavior of Liquefiable Clean Sand
Author(s) W. El-Sekelly, M.ASCE; R. Dobry, M.ASCE; T. Abdoun, M.ASCE; and M. Ni, S.M.ASCE Abstract This article presents numerical simulations investigating pore pressure buildup of a sand layer with a free drainage boundary at the top under both low and high...
Impact of Three-Dimensional Sphericity and Roundness on Coordination Number
Author(s) Wenbin Fei and Guillermo A. Narsilio, Ph.D., CEng. Abstract Coordination number (CN) is a fundamental microscale variable in soils affecting the macroscale parameters of the material such as porosity, stiffness under loading, and stability under...
