Abstract: This work investigates the reuse of natural (SCB) and aminopropyltriethoxysilane-modified (MSCB) sugarcane bagasse fibres in cementitious composites. Sugarcane bagasse fibres are pre-used in the treatment of motor oil contaminated effluents. A full factorial design is used to identify the effects of fibre type (SCB and MSCB), fibre length (0.6 and 1.2 mm), fibre amount (1 and 2 wt%) and fibre condition (before and after oil filtration) on...

Abstract: Progressive collapse is a relatively rare event which happens due to unusual loading on a structure that lacks adequate continuity, ductility and indeterminacy which causes local collapse in that structure and then extends it to other structural parts. In 2003, US defense department to published regulations UFC 4-023- 03 on the building design against progressive collapse and in 2009 submitted a revised version of the regulations. This... More

Abstract: At present, earthquakes are a serious problem for building. Severe damages and collapses of buildings were caused by earthquakes in different degrees. It is reported that there are more than 68,858 deaths and hundreds of billions RMB losses in the May 12, 2008 Great Wenchuan Earthquake [16]. So, more attention should be paid to seismic technology. In order to face the challenges of earthquake on building, the seismic retrofitting was put... More

Abstract: Due to the shortage of land in cities and population growth, the significance of high rise buildings has risen. Controlling lateral displacement of structures under different loading such as an earthquake is an important issue for designers. One of the best systems is the diagrid method which is built with diagonal elements with no columns for manufacturing tall buildings. In this study, the effect of the distribution of the tuned mass damper... More
