Research Brief: Examining Freeze-Thaw Damage at the Microscopic Scale
(2017-01-12)
Researchers conducted both theoretical and numerical studies on the microscopic phenomena in cement paste pores to reveal the important roles that ions and electrolytes play in freeze-thaw damage.
Research Brief: A break-even hazard mitigation metric
(2017-01-12)
CSHub researchers developed the Break Even Mitigation Percent (BEMP) to answer the question: “How much should be invested in mitigation for a particular building?”
The Effects of Inflation and Its Volatility on the Choice of Construction Alternatives
(MIT Concrete Sustainability Hub, 2011-08)
Life Cycle Cost Analysis (LCCA) is the standard method for costing long-lived construction projects. The LCCA process determines the full costs of mutually exclusive construction options, finding the project design with ...
Critical Issues When Comparing Whole Building & Building Product Environmental Performance
(2016-10-17)
Guides, standards, product category rules, and environmental product declarations have emerged to evaluate environmental impacts within the buildings sector. These efforts have certainly moved the field forward, but as of ...
Research Brief: Validation of Molecular Dynamics-Based Structural Damage
(2019-03)
Windstorms currently generate $28 billion in average annual damage and this figure is projected to potentially rise to $38 billion by 2075. Traditional engineering approaches that analyze the resilience of structures fail ...
Research Brief: Concrete building design optimization for reduced life cycle costs and environmental impacts
(2018-04)
Decisions made at early stages of the building design process can have a large influence on the environmental performance and financial costs of a building. One of the best ways to discover preferable designs is to analyze ...
Research Brief: Community-Informed Building-Scale Resilience Assessment
(2020-02)
It is widely known that natural hazards, like hurricanes, cause tremendous levels of damage and that hazard mitigation can significantly curb natural hazard-induced losses. However, necessary investments are still needed ...
Research Brief: Investigating the Mechanisms of ASR Using Atomistic Methods
(2020-05)
With 20% of highway pavements in the U.S. in poor condition, mitigating pavement failure has become increasingly important. However, the mechanisms of the alkali-silica-reaction (ASR), a leading cause of damage in concrete ...
Research Brief: Assessing Road Quality Using Crowdsourced Smartphone Measurements
(2020-07)
As the demands on the nation’s roads increase, so too have road maintenance costs. To meet these challenges, agencies must vigilantly monitor road surface quality to properly apportion resources. Traditional methods of ...
Research Brief: Generating Component-level Building-specific Fragility Curves
(2020-11)
One of the most essential tools for representing the vulnerability of a structure is the fragility curve. By capturing the probability of damage at a given load level, fragility curves provide a way to express how a ...
