Determination of the Characteristics of High Winds in Istanbul

It's known that the field measurements are the most reliable tool in researching the characteristics of winds near the earth's surface. Determining wind characteristics and atmospheric turbulence features bears significance in understanding wind climates in detail, the designs of the structures vulnerable to wind effect, wind turbines and wind tunnel simulations

Dynamic Response Of Multistory Reinforced Concrete Buildings Having Different Types Of Isolators A Parametric Study

Approaches to isolating the base have become a crucial element in enhancing quality stability during a seismic earthquake load. In the present day, base detachment is routinely utilized as an essential arrangement technique for structures and frameworks in seismically active zones. This paper aims towards the dynamic analysis of a multi-story RCC building with various parameters. For the sake of study and verification, a model of a ten-story RCC building with a symmetrical floor plan is considered. The study was conducted using SAP 2000's time-history-based software. In this paper,72 models were studied based on various parameters such as bay width, number of bays, number of floors, and various isolators (Lead Rubber Bearings, Friction Pendulum Bearing, Fixed, and Hinge). The reaction of the structure, for example, time period, base shear, and story displacements are studied and a comparison is made. The paper showed the clear superiority of isolation methods in resisting earthquakes. The friction pendulum support has been the preferred type due to the lowest drift story of the building when it was compared with other support systems. Also, as the results showed a high time period when using the lead rubber bearings, which shows the model's ability to withstand earthquakes

Numerical Investigations Of Effective Parameters On Multi-Story Building Having Inclined Supporting Foundations

This study deals with the use of finite element analysis to study the response of an RC building that has inclined supporting leads in the foundations. Several RC buildings were studied to evaluate the seismic performance of these buildings under the influence of change in three parameters (the degree of inclination of the foundations (0°, 10°, 20° & 40°), the storey number (8, 10, 12, 16 & 20 storey), and the span length (4, 5 & 6 m)). All buildings were analyzed using the SAP2000 software using the time history analysis method under the influence of the EL-Centro N-S 1940 earthquake acceleration record. The results were shown the values of the base shear, time period and roof displacements decreased by 23%, 33% and 55% respectively, when the degree of foundation inclination of the building increased from 0° to 20°, while these values increased by 68%, 53.28% and 137.6% respectively, when the No. of stories increased by 50%. The increase of base shear due to increase the height of building, also the increase lateral displacements of the buildings. The increases in time period due to decrease the stiffness of RC building and it have more displacements at tip of buildings
