CSHub researchers are mdeling how shear walls and sprinkler systems can mitigate hazard damage.
Research Brief: Molecular Dynamics-based Resilience Assessment of Structures
May 18, 2021

As climate change exacerbates natural hazards, the need to predict hazard damage has increased. Resilience assessment tools, however, remain time and resource-intensive.

Research Brief: Comparison of Feedforward and Recurrent Neural Networks for Predicting Pavement Roughness
January 26, 2021

While it has long been clear that the weight of traffic deteriorates pavements, the exact forms of damage it causes has remained uncertain....

This report provides a unified theoretical framework for understating two causes of premature deterioration in concrete pavements: the alkali-silica reaction and freeze-thaw damage.
A Scientific Investigation into Concrete Pavement Durability
January 12, 2021

A culmination of several years of multidisciplinary collaboration, this report by researchers from CSHub, Oregon State University, and the...

Research Brief: Investigating the Mechanisms of ASR Using Atomistic Methods
July 1, 2020

The alkali-silica-reaction, a leading cause of deterioration in concrete, has been studied extensively—yet some of its mechanisms remain unclear....

Research Brief: Simulating the Formation of ASR Gels
April 24, 2019

Alkali-silica-reaction (ASR) is a significant cause of premature concrete deterioration. While it has recieved significant scholarly attention, questions still remain about how the ASR gel can...

Research Brief: Modeling the Freeze-Thaw Damage Mechanism in Cement
January 30, 2019

In this research brief we propose a new way to understand the cause of freeze-thaw damage in cement. While conventional thinking attributes the damage to pressure generated by expansion of water...

Research Brief: A Reaction-Diffusion Model to Determine Mesoscale Patterns in Cement Paste
Research Brief: A Reaction-Diffusion Model for Mesoscale Patterns in Cement Paste
August 9, 2018

Strength and toughness, two important aspects of the durability of concrete structures, are dramatically influenced by the material's nanotexture. CSHub modeling efforts are beginning to answer...

Research Brief: Capillary Stress During Cement Drying Shrinkage
June 5, 2018

Cement paste is quite porous. When there are changes to outside relative humidity, due to rain or dry conditions, the pores inside cement can be filled with water or become empty, generating high...

Chart from research brief: Mechanical properties of Alkali Silica gels
Research Brief: Mechanical properties of Alkali Silica gels
August 17, 2017

Certain aggregates that are used to make concrete contain amorphous silica. This silica can react with alkalies in the cement paste pore solution and form a gel. This reaction is called alkali-...

Research Brief: Atomistic Modeling of ASR Gel
August 14, 2017

The Alkali-Silica Reaction (ASR) causes expansion and cracking in concrete which can result in structural problems in concrete infrastructure. ASR gel, formed from a chemical reaction between...
