Abstract: Most of current seismic design codes accept heavy damages to the building in case of large earthquakes, provided that the building is prevented against collapse. However, this acceptance leads to some unacceptable consequences in populated cities, like very great number of people who lose their residence or work place for very long time. To overcome these difficulties one approach is design of ‘repairable structures’ for buildings, by using the idea of ‘Deliberate Directing of Damage’ (DDD), which means guiding the damage to some pre-decided parts or elements of the structural system, so that other parts do not experience any plastic deformation. In this study the DDD idea has been employed for design of repairable steel buildings based on creation of building’s rocking motion possibility rather than its shear deformation, by using a central hinge support and circumferential energy dissipating columns at base level. Energy dissipation is done by a Multiple Trapezoidal Yielding Plate En

Abstract: The flow field and temperature distribution in a three-storey simple atrium building located in three different cities across Canada is numerically investigated at different times on a summer day. The building utilizes a buoyancy-driven natural ventilation system and has a curved glazed roof over the central portion. The numerical results are obtained using the commercial CFD solver ANSYS FLUENT©. The Reynolds Averaged Navier Stokes (RANS) equations are solved in conjunction with the SST- k-ω turbulence model and the Discrete Transfer Radiation Model (DTRM). Results for the ventilation air flow rate, the air pressure, the velocity, the turbulence intensity, and the temperature distribution inside the building at different times of the day are presented for the various locations considered in the study.
