Bond Between Self-Compacting Concrete And Reinforcement, Marian Sabau, Traian Onet, Ioan Pop

Marian Sabau

This paper study the bond behaviour of self-compacting concrete (SCC) in comparison to normal vibrated concrete (NVC). In this paper are presented the following parameters: the influence of bar diameter, the influence of concrete quality, the top-bar effect, the influence of active and passive confinement. In literature, different test results are found for the bond strength in SCC, which deliver contradictory results, but internationally it seems to be agreed that bond strength in SCC is slightly higher than NVC.

Hardened Properties Of Self-Compacting Concrete, Marian Sabau, Traian Onet, Ana Ioana Petean

Marian Sabau

This paper presents the properties of hardened self-compacting concrete (SCC) and compare them to those reported for normally vibrated concrete (NVC). The mechanical properties evaluated are: compressive strength, modulus of elasticity, tensile strength, creep, shrinkage and bond with reinforcement. The very wide range of materials and mixes already used for SCC produced a significant scatter of data, but clear conclusions have been obtained. The compressive strength of SCC was likely to be the same or greater than that of NVC by using the same content of cement and water. Modulus of elasticity of SCC was lower than that of NVC …

In order to successfully compete within this framework it is recommended by the authors, that Irish Government moves towards the legal mandating of BIM. This can ensure a greater …

Using Life Cycle Assessment Methods To Guide Architectural Decision-Making For Sustainable Prefabricated Modular Buildings, Jeremy Faludi, Michael Lepech, George Loisos

Dartmouth Scholarship

Within this work, life cycle assessment modeling is used to determine top design priorities and quantitatively inform sustainable design decision-making for a prefabricated modular building. A case-study life-cycle assessment was performed for a 5,000 ft² prefabricated commercial building constructed in San Francisco, California, and scenario analysis was run examining the life cycle environmental impacts of various energy and material design substitutions, and a structural design change. Results show that even for a highly energy-efficient modular building, the top design priority is still minimizing operational energy impacts, since this strongly dominates the building life cycle's environmental impacts. However, as an …

Legal Issues In Green Construction, Namrata Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

The most recent "green construction movement", made a significant impact on the design and construction industry in the United States. Organizations such as the American Institute of Architects (AIA) have lobbied governmental entities to provide financial incentives to promote green construction. The green construction community also promotes the notion that a healthier working and living environment is achieved. Due to finical incentives coupled with projected long-term energy cost savings, many owners of new construction are considering green construction as an option. Accompanying the "green construction movement", new kinds of legal issues, particularly relating to green aspects such as certification, energy …

Structural Performance Of Reinforced Concrete Flat Plat Buildings Subjected To Fire, Sara Jean George

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reinforced concrete structures are typically considered to have inherent resistance to fire. However, several concrete structures around the world have experienced partial or total collapse under fire. Reinforced concrete flat-plate is a type of structural system widely used for office and residential buildings. Flat plate construction is prone to punching shear failure at slab-column connections which may lead to a catastrophic progressive collapse. The slabs of flat-plates generally have very thin concrete cover leaving steel reinforcement more sensitive to thermal loads. Little is known in the engineering community about the structural performance of flat-plate structures subjected to fire. Through a …

Assessing Impermeable Surface Area Impacts On Modeling: Implications For The Combined Sewer Overflow Long Term Control Plan In Omaha, Nebraska, Andrew D. Szatko

Community and Regional Planning Program: Professional Projects

The report looks at assessing the accuracy of estimating impervious surface areas (ISAs) by zoning code, the method utilized by the City of Omaha, Nebraska. A 101 acre subcatchment had all ISAs manually digitized and compared the actual with the estimated value. The subcatchment was then modeled with 10 percent decreases of ISAs to establish the relationship with peak flow rates and total volume in the combined sewer service area. The results show a significant relationship between the two that may provide insights into a new approach to manage CSO events with the integration of green infrastructure.
