Cultural heritages and historical buildings are vulnerable against severe threats from fire. Since the 1970s, ten fire-spread events involving historic buildings have occurred in Taiwan, affecting a total of 132 nearby buildings. Developed under the influence of traditional Taiwanese culture, historic buildings in Taiwan are often built using non-fire resistant brick-wood structure and located ...

This study investigates the seismic behavior of deconstructable composite steel/concrete floor systems consisting of precast concrete planks and deconstructable clamping connections attaching the planks to the steel floor beams. The system is proposed to promote sustainable design of composite steel/concrete floor systems in steel buildings via reuse of the structural steel and concrete compone...

Characterization of structural woods in historical buildings has a great importance in technological study of applied details. Herein, seven historical buildings located in Alborz, Isfahan and eastern Azerbaijan provinces related to Safavid and Qajar periods have been assessed. Samplings were done from structural woods of the buildings. Samples were prepared, sectioned and evaluated by transiti...

in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...

This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...

Odors are emitted from a variety of sources in swine production facilities. A large quantity of odorants can be emitted from manure handling and storage facilities. However, swine production buildings can also emit significant levels of odorants. This is especially true if manure is held within the buildings for periods exceeding 4-5 days. Manure also sticks to floors, walls, equipment, and pig...

plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...
