RISGreen Concrete with High-Volume Fly Ash and Slag with Recycled Aggregate and Recycled Water to Build Future Sustainable Cities
Publisher: American Society of Civil Engineers
Tests of Cold-Formed Circular Tubular Braces under Cyclic Axial Loading
Publisher: American Society of Civil Engineers
Abstract: This paper describes a series of tests to failure of fix-ended tubular braces subjected to cyclic concentric axial loading. The braces were made from cold-formed steel grade C350L0 (350 MPa nominal yield stress) circular ...
Curing Conditions of Alkali-Activated Fly Ash and Slag Mortar
Publisher: ASCE
Abstract: This study compared the effect of seven common curing conditions on the compressive strength, pore alkalinity, efflorescence, and shrinkage of five alkali-activated fly ash and slag (AAFS) mortars and one cement mix. The ...
Cyclic Bending Tests to Determine Fully Ductile Section Slenderness Limits for Cold-Formed Circular Hollow Sections
Publisher: American Society of Civil Engineers
Abstract: This paper determines new section slenderness limits suitable for design and construction of seismic resisting structural systems. It describes an experimental investigation of the cyclic inelastic flexural behavior of ...
Closed-Form Solution to the Poromechanics of Deep Arbitrary-Shaped Openings Subjected to Rock Mass Alteration
Publisher: ASCE
Abstract: The aim of this paper is to propose a closed-form solution to the poromechanics problem of stress and pore pressure distribution around noncircular openings at great depth subjected to hydrostatic water pressure and far-field ...
Flexural Behavior and Rotation Capacity of Welded I-Beams Made from 690-MPa High-Strength Steel
Publisher: ASCE
Abstract: In this study, the flexural behavior and rotation capacity of welded I-beams made from 690-MPa high-strength steel were investigated through experimental tests and numerical simulations. In the experimental program, a total ...
Experimental Study on Composite Beam with Various Connections under Midspan Impact Scenarios
Publisher: ASCE
Abstract: The performance of an immediate frame span subjected to a falling-debris-impact scenario is of great importance to investigate the spread of initial damage during a progressive collapse event. If the frame span was not ...
Enhanced Fire Resistance of Double Web Angle Cleat Connections with Austenitic High-Strength Bolts during Furnace Fires
Publisher: American Society of Civil Engineers
Abstract: Natural fire incidents and standard fire tests have demonstrated that flexible and semirigid connections have suffered premature failure due to the temperature sensitivity of the quenched and tempered carbon steel bolts, ...
Experimental and Theoretical Investigation on Flexural Behavior of LWSCC Beams Strengthened with an ULW-ECC-FRP Mesh Layer
Publisher: American Society of Civil Engineers
Abstract: The structural performance of lightweight self-consolidating concrete (LWSCC) structures is susceptible to degradation due to its inherent brittleness. To address this challenge, the ultra-lightweight engineered cementitious ...
Circular Concrete Columns and Beams Reinforced with GFRP Bars and Spirals under Axial, Eccentric, and Flexural Loading
Publisher: ASCE
Abstract: Glass fiber-reinforced polymer (GFRP) reinforcement has been considered as a replacement for the traditional steel reinforcement, mainly due to its corrosion resistance. In this paper, a total of 13 concrete columns and ...
