Many cities in the world are involved with air pollution and environmental pollution. The consumption of fossil fuels in buildings has an enormous impact on the pollution. About 40% of the total energy is spent on heating, cooling and lighting of buildings. The use of solar energy is one of the ways that reduce the thermal load of buildings. One of the factors that affect this utilization is th...
Background and objective: Earthquake is one of the most destructive natural disasters. Earthquakes occur in urban areas, destroying buildings and injuring people living in them. Urban center buildings are among the features that are exposed to many hazards during an earthquake. One of the first measures taken after an earthquake is relief. Locating damaged buildings can speed up relief efforts....
this article, describes five archival buildings in england, australia, and switzerland. these buildings are conformed with universal standards. it also examines the records' linear feet and their preservation methods.
the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...
various view points of the library planners about the future’s library buildings have been explained in this paper. with the advances in information technology, some librarians believe that modern and well planned library buildings are not so necessary in the future. on the other hand, many others believe that more modern and well technologically equipped library buildings should be built to fu...
Earthen building materials have been in common use as cheap, available, and practical construction materials in hot and dry areas for a long time. Earthen buildings exist in Iran, especially in villages, because of the large and numerous areas that have the same climate. Given that Iran is highly earthquake prone and the importance of paying attention to the possible vulnerability of all the in...
Agriculture has been a widespread activity in Kashan since a long time ago which has developed traditions and local skills. The said traditions and skills of earning living from farming has created a system which could be recognized as an agricultural heritage due to its values. This heritage possesses significant structural dimensions; as the form and feature of farms as well as their location...
response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...

Information Technology until recent years mainly have been driven by technological possibilities based on research methods developed within engineering and natural science. The capacity and the ever-decreasing size of IT enable penetration into almost any object. IT can no longer be regarded as an isolated technological possibility; through networks and telecommunication it has become an integr...
