Re: About beamless slab curtain ratio Hello, in TBDY 2018, there is no sanction for curtain ratio control in beamless tiled systems. As stated in Article 4.3.4.4, in systems with non-beam slabs, all earthquake effects will be covered by hollow/non-gap shears (Choosing the carrier system type A12 or A13), the calculation will be made in two stages, and the frame columns will be modeled as hinged from the bottom and top in the first stage calculation, and in the second stage, the element connections will be calculated. It is stated that the monolithic model will be modeled and the design will be made according to the most unsuitable situation. In the program, the design is made automatically according to the two-stage calculation and the most unsuitable loading, and the necessary information is given in the reports. Good work
