Bubbledeck, Purdue Ect Team

ECT Fact Sheets Archive

Conventional horizontal concrete slabs are heavy that limit their spans. Enhancement of span results in addition of beams that increases the cost of the structure. Thus, there is a need for a technology that will help in increasing the span by reducing weight of the span. BubbleDeck is a revolutionary construction method that virtually eliminates concrete from the middle of a floor slab between columns that does not perform any structural function, thereby dramatically reducing structural dead weight. BubbleDeck is based on a patented technique - the direct way of linking air and steel.

Opportunity Lost: Mismanagment Of The Closeout Phase Of Construction Projects, Jared Rogers

Purdue Polytechnic Masters Theses

In nearly every construction project, completing the project on time is one of the most critical things for everyone involved. Late project completion causes a wide variety of complications for the entire project team. This paper seeks to identify some of the causes for delay in the last phase of construction projects: the closeout phase.

Original research was conducted to gather input from construction industry professionals about their experiences with the closeout phase of projects. Factors perceived to cause closeout delay were identified, along with perceptions about the closeout performance of survey participant’s firms. The research validated the study’s premise …

Gis Based Pavement Maintenance: A Systematic Approach, Robert J. Kmetz

Purdue Polytechnic Directed Projects

Abstract

According to 2008 Federal Highway Administration (FHWA) statistics, there are 2,734,102 miles of paved public roads in the United Sates, with an additional 1,324,245 miles of unpaved public roads.  Road conditions deteriorate with time as the result of weather effects, deicing salts, and vehicle loads.  The most common pavement distress includes cracking, rutting, and potholes.  These pavement defects must be repaired to restore the pavement to a satisfactory service level for road users. According to the FHWA, in 2006 approximately $54.2 billion dollars was spent on maintenance and expansion, just on U.S. highways alone.

Routine maintenance is a cost …

Sustainable Design Optimization Of Rural Houses In North China, Mingliang Li

Purdue Polytechnic Masters Theses

With the rapid economic development of China, the living standards in rural areas have been experiencing improvement over the past two decades. One important aspect of the improved living standards is housing, which has been transformed from traditional adobe or stone structures into modern brick and concrete ones. In the meantime, active heating and cooling systems are gradually being incorporated and residents are requiring more comfortable indoor air temperatures during cold winters and hot summers. However, most rural houses have no insulation in their exterior walls and roofs. The question is whether or not it is economically viable to build …

New Structural Material - Fiber Reinforced Plastics, Purdue Ect Team

ECT Fact Sheets Archive

Traditional structural materials are heavy and require a great deal of maintenance. If a new breed of structural material could be produced that was lighter, stronger and more resistant to corrosion, impacts, parasites and chemicals, it could be a good substitute for steel, concrete, masonry and wood. One new material that has the potential to meet these demands is starting to show up on the construction industry market, it is Fiber Reinforced Plastics (FRP). Some technologies that have been developed using FRP materials within the last few years are: structural shapes, concrete reinforcing, prestressing and post-tensioning tendons and pre-engineered structural …

Post-Tensioned Steel Structure, Purdue Ect Team

ECT Fact Sheets Archive

Welded steel Moment-Resisting Frames (MRFs) were long considered as one the most earthquake-resistant types of structures. Recently, the idea of applying the post-tensioning technology to achieve moment resistant structural systems has been investigated at the University of California, San Diego. Since 1996, moment-resisting connections using post-tensioning concepts have been developed and tested for precast concrete beam-to-column connections, and concrete shear walls.
