Research paper thumbnail of The Effects of Height and Plan on the Along-Wind Response of Structures Considering Wind-Soil-Structure Interaction

In this work, the simulation of the wind and soil effects on the high-rise buildings are done numerically using the ABAQUS software. The wind-induced vibration of the building models is studied through Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD). Co-simulation is accepted for the transfer of loads from the fluid to the structural domain. The mechanical response of the soil system is modeled using direct method. Suitable contact elements for slippage and separation modeling between subsurface elements are also considered. Finally, fluid and structural responses are compared in terms of mean and root mean square values with laboratory results on the wide range of reduced velocities. It is concluded that height and cross-section of building affect the vibrational response of the building, and therefore the designer must carefully consider these factors in order to ensure that the design is safe.

Research paper thumbnail of Behavior Factor of Flat Double-Layer Space Structures

Journal of Civil and Environmental Engineering, 2012

Flat double-layer grid is from category of space structures that are formed from two flat layers ... more Flat double-layer grid is from category of space structures that are formed from two flat layers connected together with diagonal members. Increased stiffness and better seismic resistance in relation to other space structures are advantages of flat double layer space structures. The objective of this study is assessment and calculation of Behavior factor of flat double layer space structures. With regarding that these structures are used widely but Behavior factor used to design these structures against seismic force is not determined and exact, the necessity of study is obvious. This study is theoretical. In this study we used structures with span length of 16m and 20 m. All connections are pivotal. ANSYS software is used to non-linear analysis of structures. Keywords—Behavior factor, Double-layer, Intensified resistance, Non-linear analysis

Suspendomes are single-layer braced domes reinforced with cable and strut. Prestressing of cables alter value and distribution of stress in structure. In this study two configuration, diamatic and lamella domes is selected. Investigated domes have span of 100m with rise-to-span ratios of 0.1, 0.2, and 0.3. Single layer domes loaded under service load combinations according to ISO code. After geometric nonlinear analysis, models are designed with tubular and I-shaped sections then reinforced with cable and strut and converted to suspendomes. Displacements and stresses of some groups of nodes and elements in all of single-layer domes and suspendomes for three load combinations, symmetric snow, asymmetric snow and wind are compared. Variation due to suspending system is investigated. Suspendomes are redesigned and minimum possible weight after addition of cable and strut is obtained. Keywords—Braced dome, Pre...
