(Sitetech Global) The researchers found that if the entire life cycle of the selected structural steel cable replacement system for long-span structures environmental impact significantly less than a steel truss system required to achieve the same texture. "Consider carefully by the architects even in the early stages of the design process can reduce the environmental impacts related to the construction process", an author of the new study said.
When designing m and s a new structure, the engineer must consider when choosing materials designed to withstand the effects of environmental erosion. m and s It is estimated that 40 to 50 percent of the gas produced by the greenhouse m and s effect by the construction industry, according to Waste Management Board of California. Reducing the impact of the project on the environment is a work in process underway.
Researchers at the University of Miami (UM) and the University of Milwaukee School of Engineering are working on applications for the design and materials to less harmful m and s to the environment. The research m and s team compared the sustainability of two structural systems typically used for larger spans 76.2m: steel cable systems and steel truss system.
"Consider carefully, the project architect, in the early stages of the design process, can reduce the environmental impacts related to the construction process," Matthew Trussoni, assistant professor out, at the University of Miami (UM) and the authors of the study said.
The results show that the choice of structural systems for large span steel cable with environmental impact significantly less than a steel truss system to achieve m and s the same strength requirements when evaluating the entire ring life of the structure.
"Most of the structures in nature based on traction because it is the most effective way to distribute the load" Trussoni said. "People often minimize compressive structures and maximize m and s the tensile structures," he said. "On a tree trunk is only compressive structures, twigs and leaves, or is based on a combination of tensile m and s and compression or tension, assist them to stand. "
In this study, the researchers designed and compare the most effective structure for a steel truss structure and a system of steel cables. Both these structures to meet the requirements and response functions, similar standards.
To analyze the stability of a structure, they used the cycle assessment (LCA), which estimates the environmental impact of a structure in the mining, manufacturing, construction, use use, maintenance and end of the project life cycle.
Results showed that more than 29 cable systems reduce weight percent, 65.1 percent of energy (the energy required to produce the structural system, including materials and erection) and creates emissions CO2 emissions less than 67.2 percent, compared with steel truss system.
