Building base reaction calculations with different analys methods for draft Turkish Building Design Codes 2016 for earthquake resistance and other building design codes

SUMMARY The present thesis aimed to give alternative suggestions about behaves of buildings under the earthquake situation. Creation of the suggestions were considered based upon the worst case scenarios and real life scenarios. Equivalent seismic load method, linear elastic, modal methods and time history constitute the mentioned earthquake situations. Therefore template Turkish Earth Quake Regulations were investigated and presented to the engineers in improved version. TBDY-2016 base shear force are classify as an earthquake load. Hence that load were investigated. Also linear and nonlinear effects were examined during the present work. So accuracy of the result searched compared and investigated .İf the result from the base shear force calculation illustrates higher result from the linear method, thus showed us the existence of mistakes. Or if the results are low, it shows the existence of the inappropriate structural design. The present work suggest to compare and proportion all calculation methods based on Equivalent seismic load method. Therefore the proportion ratio should between 0.8-1,5. Template Turkish Earth Quake Regulations 2016 include reduction factor of seismic load and Equivalent seismic load method. According to the Equivalent seismic load method, effect of same amount of base shear force to all buildings can cause to higher overturn moment by the additional equivalent seismic load. Overturn situation are occurred frequently for the high rise buildings. So the regulations must be revised as od regulations and "base shear force should be lower than 20%" rule should take place at the new regulation. Time history calculations should have acceleration coefficient. So that coefficients should be determined and prerequisite situations should be determined to illustrate condition of use. Prerequisite conditions can be archived by the investigating of the earthquake class of the area or using the specified earthquake area information that shows great similarities. However using similar area information can cause some difficulties. Equivalent seismic load are site-specific loads. Hence earthquake analysis should be revised and calculated again for the new area. As a result the analysis of a building are calculated or performed by the predetermined assumptions. Although the transferred model of building to the computer software are perfect, the mistake occurrence are possible. Thus investigating of building according to the total earthquake load is much more appropriate to investigating of buildings according to the design of building elements.
