Impact of Local Soil Properties on Rough Cost of Building in DBYBHY07
AbstractIn this study; The typical plan of the same 8-storey reinforced concrete building, the change in the cost of rough construction due to the change in soil engineering properties for different earthquake zones were investigated. The building designed to show the cost change; First Degree, II. Degree, III. Degree IV. Degree Earthquake Zones, non-earthquake status and changing soil classes (Z1, Z2, Z3, Z4) were considered to be. Static and reinforced concrete designs are designed in accordance with TS500 and DBYBHY07, making sure that there are no irregularities and that the project is symmetrical. The designs were made by using modal analysis method with the help of Sta4CAD (v13.1) package program. Carcass (concrete, steel and formwork) construction quantities obtained due to different earthquake zones and different soil classes were extracted. According to the results, the unit prices of the Ministry of Environment and Urbanization (2019) and the carcass system cost of each structure were calculated. The total cost values have been revised and comparisons have been made depending on the results of the quantities, soil classes and earthquake zones. Cost change In the Z4 soil class, an increase of 18.8% was observed in the earthquake-free situation compared to the 1st Degree Earthquake Region and 9.5% compared to the 4th Degree Earthquake Region.
