Size Effect on Nominal Strength of Lightweight and Normal Concrete-Filled Steel Tube Columns under Axial Compression: Mesoscale Simulations
Publisher: ASCE
Abstract: With the devolvement of large-span structures and super high-rise buildings, lightweight aggregate concrete (LWAC) materials have been widely utilized. The main content of this work is to explore the failure and size effect ...
Mesoscale Modeling and Simulation of Size-Dependent Shear Response of Rectangular CFRP-Confined RC Columns
Publisher: ASCE
Abstract: Reinforced concrete (RC) columns are prone to shear failure under seismic loads, particularly in the case of short columns. However, this brittle failure may have more adverse effects on large-sized columns. To address ...
Size Effect on Compressive Strength of GFRP-Confined Concrete Columns: Numerical Simulation
Publisher: ASCE
Abstract: The available researches on concrete columns confined with fiber-reinforced polymer (FRP) laminates have not comprehensively addressed the size effect. In this study, a three-dimensional mesoscale simulation approach that ...
