The "greening" of the concrete industry : factors contributing to sustainable concrete
(Massachusetts Institute of Technology, 2006)
The dawn of the new millennium has brought to light the environmental concerns of global warming, pollution, limited landfill space, and depleting natural resources. These concerns, compounded by the growing global population, ...
Collection and representation of GIS data to aid household water treatment and safe storage technology implementation in the northern region of Ghana
(Massachusetts Institute of Technology, 2006)
In 2005, a start-up social business called Pure Home Water (PHW) was begun in Ghana to promote and sell household water treatment and safe storage (HWTS) technologies. The original aim of the company was to offer a variety ...
High modulus carbon fiber/titanium laminates
(Massachusetts Institute of Technology, 2006)
Titanium has been used to meet ever-stricter standards for high-temperature performance, creep resistance, low weight and high strength. Having low density, a high melting point, and high tensile strength, it seems like ...
A performance based approach for seismic design with hysteretic dampers
(Massachusetts Institute of Technology, 2006)
Current trends in structural engineering call for strict performance requirements from buildings prone to extreme earthquakes. Energy dissipation devices are known to be effective in reducing a building's response to ...
Application of knee-bracing system on high-rise buildings
(Massachusetts Institute of Technology, 2006)
The need and ambition of humanity to go higher and higher is something that is amplified as time evolves. It is the same need that leads engineers to push their structures to higher limits. However, when engineers design ...
Reliability of corroded steel bridge girders
(Massachusetts Institute of Technology, 2006)
Corrosion is one of the main causes of deterioration of bridges. Structures exposed to harsh environmental conditions are subjected to time-variant changes of their load-carrying capacity. Thus, there is a need for an ...
Motion control of long span horizontal structures
(Massachusetts Institute of Technology, 2006)
Traditional approaches to structural design presuppose strength to be the dominant design requirement. But following new technologies and design methods, this assumption that strength requirements dominate is being challenged. ...
The progressive synthesis of architecture and engineering in modern bridge design
(Massachusetts Institute of Technology, 2006)
History states that architects and engineers rarely operate in a peaceful environment as each have their own specific agendas to fulfill. The architect appeals to the plastic form of a building before tending to its ...
Water demand management in Kuwait
(Massachusetts Institute of Technology, 2006)
Kuwait is an arid country located in the Middle East, with limited access to water resources. Yet water demand per capita is much higher than in other countries in the world, estimated to be around 450 L/capita/day. There ...
Analysis of crack patterns in reinforced concrete frames under seismic excitation
(Massachusetts Institute of Technology, 2006)
Earthquakes occur as a result of sudden displacements across a fault within the earth. The seismic waves that result from them propagate along the earth's surface and are the cause of multiple damages especially in civil ...
