The use of TS498 and TS-EN-1991-1-4 in the Wind Load Calculation of Reinforced Concrete Minarets Considering Soil-Structure Interaction

Abstract

The minarets are among the most beautiful, meaningful and delicate works of Islamic architecture. At early times, although these slender structures were built short and with masonry stone, as time progressed, the construction of minarets with reinforced concrete and that are thin-walled and long were preferred. This has caused many reinforced concrete minarets to be damaged or destroyed under wind and earthquake forces. With regard to this issue, because of the severe winds, many minaret collapse incident took place in Turkey. Due to this reason, in this study, the wind loads acting on a selected reinforced concrete minaret have been calculated in details according to TS498 and TS-EN-1991-1-4 standards. In the calculations made, the effects of soil structure interaction on the calculated wind loads were also examined. At the end of the study, the wind loads obtained in the calculations were compared. The obtained results show that soil structure interaction is a negative effect on wind loads, this interaction increases them and that the soil structure interaction should be included in wind load calculations.

“…As the procedures of the cited standards are open to public, there is no need to define all of the symbols in the wind load calculations. One can obtain the details of the wind loading calculations in these studies [55][56][57][58][59]. Also, in these wind load calculations, basic wind speed is taken as 45 m/s.…”
