soft fold irregularity

[aliharmanci]

Prof.Dr.Semih TEZCAN, in one of his conferences, strongly says that if there are soft floors in buildings, the effect of infill walls on rigidity should be taken into account. However, we do not consider the effect of walls on stiffness in design. What should be done in this case?

Re: SOFT FLOOR IRRORITY

Prof.Dr.Semih TEZCAN, in one of his conferences, strongly says that if buildings have soft floors, the effect of infill walls on rigidity should be taken into account. We do not take into account the effect of walls on rigidity. What should be done in this case?

17.2.3- Where the design rules described in this section are used for buildings whose load-bearing system consists only of frames, infill walls made of brittle material or between facade elements and frame elements 4.9. Flexible joints or joints should be created according to 1.3(b) 4.9.1.3(b) TBDY page 56

Hello there; prof. Dr. It is an important issue here that Semih Tezcan gave this information regarding the situation. If there is a soft storey, 1- Modal analysis methods should be used as per TBDY 2018 3.6.2.1, equivalent earthquake load method should not be used. 2- In order to separate the infill wall effect from the structure, the infill wall should be kept separate from the structure by using the flexible joint in TBDY 2018 EK 4C. ** Considering the infill wall effect in terms of the rigidity of the system is not meaningful in the DGT calculation. Although infill walls contribute to the system rigidity, since they are brittle elements, it is included in the regulation to separate them from the building elements with flexible joints in order to provide the targeted ductile behavior. At the same time, it is difficult to ensure the quality of workmanship in the field. To take into account the material models for the infill wall, and the detailing of the element models are required. For detailed information on the subject, Prof.Dr. Zeki Hasgür and Assoc. You can benefit from the articles where our teachers, Beyza Taşkın, explain their work on structures with infill walls. Good work.
