Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project …

Modular House Revival, Kevin Chiang, Spencer Dilley, Sarah Dowthwaite, Trevor Houghton, Ryan Lefebvre, Michele Leung, Cameron Lober, Chris Martinez, Katie Mayer

Architectural Engineering

The Modular House, located in Poly Canyon, has seen extensive damage since the last caretaker left nearly ten years ago. To prevent further damage and improve the safety and appeal of the structure, we are proposing a renovation of the existing building that removes the existing cladding and partitions. By the end of Spring Quarter 2017, the Modular House will have a guardrail system replacing the wood paneling on the walls and a new steel composite deck to replace the current flooring system. The structural steel framing system will remain as is.

Compact Facility For Testing Steady And Transient Thermal Performance Of Building Walls, Aimee Byrne, Gerard Byrne, Anthony Robinson

Articles

Energy efficiency retrofit of buildings represents a key effort in reducing EU energy demand by 20% by 2020. However, predictions tend to overestimate savings by large percentages. The shortfall in savings can be attributed to incorrect predictive techniques, comfort takeback along with other behavioural and workmanship variables. Common predictive techniques related to heat loss tend to be based on the U-value of the building envelope. This paper presents the design of a more straightforward and compact version of the traditional Hot-Box apparatus (measures U-value) which instead determines the thermal resistance of samples of building envelope. U-value includes the need to …

Civil & Environmental Engineering Faculty Publications

Presented herein is the outcome of a study of prestressed concrete inverted tee beams with carbon fiber reinforced polymer (CFRP) sheets for possible use in building structures. To determine an effective approach for the use of CFRP, nine different retrofitting schemes are investigated for a prestressed beam under quasi-static distributed load to increase flexural strength. The theoretical analysis is based on coupling moment-curvature relations with a central finitedifference formulation. Three different thicknesses of CFRP sheets are studied in both tension and compression and effective retrofitting schemes are identified.

Free Fall Of Self-Consolidating Concrete In Walls Three Meters High, Donald J. Phillippi, Katie Loughmiller, Ray Buyle, Michael Cesena

The Professional Constructor

Self-consolidating concrete, (SCC) is a highly flowable, non-segregating concrete that allows for concrete placement without vibration or external consolidation. SCC also allows rapid concrete placement with reduced labor costs, resulting in vastly improved concrete surface finishes and architectural applications (RMCAO 2009). To accomplish SCC, the concrete industry has developed improvements in high-range water reducer admixtures for flowability and viscosity-modifying admixtures for stability. The current project investigated six specimens, which provided an evaluation of SCC allowed to free fall 3 m (10 ft) that filled wall formwork with different inclinations and amounts of steel reinforcement. The purpose of the investigation was …

Mechanical And Thermal Evaluation Of Different Types Of Pcm-Concrete Composite Panels, Dervilla Niall, Oliver Kinnane, Roger West, Sarah Mccormack

Conference papers

ABSTRACT: Thermal mass indicates the ability of a material to store and release heat and is a function of the heat storage capacity of a material. The thermal mass of construction materials can be used to reduce the energy required for heating and cooling buildings. The heat storage capacity of concrete can be increased by incorporating phase change materials (PCMs) into the concrete and hence providing additional latent heat storage capacity. Research was carried out to compare the thermal behaviour of two different types of PCM/concrete composite panels. The first type of panel was formed by adding microencapsulated paraffin to …
