in the conditions in which terrorist attacks on facilities and civilian places increase more and more attention to design of structures against impact loads of explosion is more important and needs special considerations. study of nature of blast loads and methods of applying it on the structure is one of the important problems. explosion is a sudden and rapid release of a great amount of energ...

Although several studies have investigated the effect of degradation on the behavior of structures, investigations on collapse margin ratios are rare in the literature. In this study, the effect of strength and stiffness degradation on collapse capacity of steel moment frames is investigated. The aim is to determine margin of safety against collapse using a probabilistic approach. For this reas...

In this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. Seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. The finite element modeling technique (SAP2000 Software) is used for analysis. Time History analyzing was done to achieve this purpose. For nonlinear dynamic analysis, the responses of ...

To meet the dual challenges of climate change and peak oil, high-performance (lowenergy) buildings must be the rule rather than the exception. Typical buildings today frequently do not deliver the energy performance predicted by designers or desired by the owner. One of the primary reasons for this failure to perform is that building control systems are not designed, installed and/or operated a...

Introduction: Over recent years, various programs have been conducted to reduce noise, indicating the increasing concerns of society over noise pollution. This study has been performed to enhance the performance of parallel barriers on two sides of a highway considering the surrounding buildings. Material and Methods: The 2D boundary element simulation method was employed to predict the noise ...

Development which is less attention to the environment, inefficient use of energy as well as the increasingly dense city make space for the concept of green building to grow even more in Indonesia . The purpose of this study was to determine the extent to which the implementation of green building principles in commercial buildings. There are three buildings complexes that were examined in this...

The inappropriate indoor environmental quality of a building causes different problems such asheadache and breathing difficulties which are called the syndrome of building sickness. These diseases reduce the efficiency of people and deteriorate the quality of their life. Studies carried out in hundreds of big office buildings across the world show that the indoor environment qualities of these ...

This paper focused on energy consumption and carbon emission for heating and cooling during a building’s operation stage, and examined the energy effects of using Cross Laminated Timber (CLT) as an alternative building material to reinforced concrete (RC) in China’s 31 key cities located in different climate zones. The authors designed two seven-story residential buildings, which were construct...

In this paper, Chi Lin Nunnery, the imitation of early Tang-Dynasty timber-structure building in Hong Kong, is used as an example to perform 3D model reconstruction and demonstrate the assembling process, as well as make a digital database of buildings. This paper gives an introduction to the features of ancient Chinese timber-structure buildings and also the workflow of 3D reconstruction of an...
