Hello.. 1-) According to what do I make the ductility level high, mixed or limited? 2-) Do I need to analyze according to a fully rigid diaphragm or semi-rigid diaphragm?
1-) You will decide on the ductility level by taking into account the conditions specified in TBDY 2018. You can examine Article 4.3.3 Table 4.1 (High ductile solution can be made under all conditions) 2-)Semi-rigid diaphragm method According to TBDY 2018 Article 4.5.6.3, the solution can be made in all conditions. Full rigid diaphragm acceptance can be made in cases where the floors are of sufficient thickness and there are no large gaps. According to TBDY 2018 Article 4.5.6.3, it says that full rigid diaphragm can be accepted in regular structures where there is no A2 and A3 irregularity. and it does not allow a solution according to the assumption of a fully rigid diaphragm in unidirectional threaded floors.
