Performance Of No Vibration/No Admixture Masonry Grout Containing High Replacement Of Portland Cement With Fly Ash And Ground Granulated Blast Furnace Slag, Eric Bateman 2014 California Polytechnic State University

Performance Of No Vibration/No Admixture Masonry Grout Containing High Replacement Of Portland Cement With Fly Ash And Ground Granulated Blast Furnace Slag, Eric Bateman

Master's Theses and Project Reports

When hollow concrete masonry is used for construction in high seismic regions, structural designs typically require fully grouted walls. The grouting process is labor-intensive, time-consuming and has a high energy demand due to requirements of consolidation in each and subsequent grout lifts. Self-consolidating grout with admixtures has been successfully used without segregation in walls of up to 12.67 ft. in height. Investigation of self-consolidating grout mixes without admixtures has potential for sustainability improvement.

This thesis reports on the compression strength and consolidation observations of self-consolidating characteristics of no vibration/no admixture grout made by substituting various proportions of Portland ...

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu 2013 Purdue University

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu

The Summer Undergraduate Research Fellowship (SURF) Symposium

Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a ...

Collective Chord Behavior In Large Flexible Diaphragms, J. W. Lawson, C. N. Yarber 2013 California Polytechnic State University

Collective Chord Behavior In Large Flexible Diaphragms, J. W. Lawson, C. N. Yarber

Architectural Engineering

The seismic behavior of large low-rise buildings with rigid walls and flexible diaphragms will be dominated more by the diaphragm’s seismic response than by the very stiff vertical walls. For practitioners, estimating the stiffness of large flexible diaphragms is important for computing building setbacks from property lines and adjacent structures as well as evaluating structural integrity under seismic loads. In addition, researchers attempting to accurately model a building’s dynamic behavior need to assemble an accurate diaphragm stiffness prediction. The traditional diaphragm chord model consists of a single continuous line of axial resistance at the diaphragm boundaries; however, as ...

Precast Concrete Insulated Wall Panel Corbels Without Thermal Bridging, Mohamed Elkady 2013 University of Nebraska - Lincoln

Precast Concrete Insulated Wall Panel Corbels Without Thermal Bridging, Mohamed Elkady

Construction Systems -- Dissertations & Theses

The common practice in corbel design is to block out the insulation in order to provide a solid concrete area at the corbel location. This connection practice results in thermal bridging, which significantly reduces the energy performance of the panel. For example, the PCI Design Handbook indicates that the reduction in thermal resistance caused by a solid part with an area equal to 9% of the total panel surface area is as high as 42%. This paper presents a discussion of a new concept for corbel design of insulated wall panels with the thermal break totally preserved. Two different designs ...
