Increasing the population, urbanization has led to the rapid construction of buildings. Due to space constraints and an increase in land cost, these buildings are built too close to each other and can cause damage under dynamic actions such as earthquakes. A new technique, known as Structural coupling, has been developed recently, has found very effective in dissipating the dispersive vibration...

Healthier space need not be new space. In fact, some new buildings are extremely unhealthy as chemicals leach out into the air from glues, carpets, concrete and paint. There is no reason this must be the case. The cost to provide healthier environments is modest compared to the benefits. Healthier buildings reduce sick time and increase productivity, making it easier to recruit and retain emplo...

Results of damage prediction in buildings can be used as a useful tool for managing and decreasing seismic risk of earthquakes. In this study, damage spectrum and C4.5 decision tree algorithm were utilized for damage prediction in steel buildings during earthquakes. In order to prepare the damage spectrum, steel buildings were modeled as a single-degree-of-freedom (SDOF) system and time-history...

abstract   iran has many historic cities and villages with economic, historic and cultural values facing with many seismic faults. there have been no comprehensive studies about reducing the vulnerability of the historic villages, and the available documents describe the retrofitting experiments only about the single buildings.  lack of a comprehensive look at the subject leads to the loss of t...

building pounding occurs between two adjacent buildings with small gap or without sufficient separation distance. it leads to damage buildings during earthquake due to impact. many researchers have investigated building pounding based on impact force reduction and energy dissipation increase, when two buildings collide with each other. in numerical investigations, using specific link element, i...

Hexagrid structural system is an innovated system with structural behavior which is similar to a tubular system. In this paper, a numerical study is conducted to estimate the seismic performance of horizontal hexagrid concerning the combined horizontal and vertical hexagrid, tubular and diagrid structural systems. First 30 and 50 story buildings are modeled using ETABS, then pushover and nonlin...
