RISAsynchronous Spacetime Discontinuous Galerkin Formulation for a Hyperbolic Time-Delay Bulk Damage Model
Publisher: American Society of Civil Engineers
Abstract: A bulk damage formulation is presented for failure analysis of brittle materials under dynamic loading. A time-delay ordinary differential equation (ODE) is used to model damage evolution. The evolution is driven by the ...
Novel Cement-Free UHPC with High Gamma-Ray Resistance Using Calcium Oxide–Activated Slag, Iron and Barite Powders, and Steel Fibers
Publisher: American Society of Civil Engineers
Abstract: This study focuses on the development and evaluation of a novel cement-free gamma-ray-resistant ultrahigh-performance concrete (UHPC), known as UHPC-CAS. UHPC-CAS is composed of calcium oxide–activated slag, iron and barite ...

Experimental and Numerical Assessment of Woodframe Sheathing Layer Combinations for Use in Strength-Based and Performance-Based Design
Publisher: American Society of Civil Engineers
Abstract: Woodframe buildings are unique in that the nonstructural finishes such as gypsum wall board and stucco provide significant stiffness and strength relative to the lateral force resisting system, e.g., wood shear walls. ...

Displacement-Based Design of Buildings with Torsion: Theory and Verification
Publisher: American Society of Civil Engineers
Abstract: Direct displacement design (DDD) is a procedure that allows one to distribute the forces induced by an earthquake to the levels of a multistory building to ensure that the desired level of interstory drift is not exceeded. ...
Effect of Volume Element Geometry on Convergence to a Representative Volume
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: To accurately simulate fracture, it is necessary to account for small-scale randomness in the properties of a material. Apparent properties of statistical volume element (SVE) can be characterized below the scale of a ...
Effects of Synthetic Fibers and Different Levels of Partial Cement Replacement on Mechanical Properties of UHPFRC
Publisher: ASCE
Abstract: This paper presents the results of an experimental study conducted to investigate the effects of polypropylene fibers and synthetic macrofibers (barchip) with different partial cement replacements on the mechanical properties ...
Full-Scale Experimental Investigation of Second-Story Collapse Behavior in a Woodframe Building with an Over-Retrofitted First Story
Publisher: American Society of Civil Engineers
Abstract: Soft-story woodframe buildings have been identified as a disaster preparedness problem throughout California and are present in many other states of the United States. These buildings can be readily identified by their ...
