Hello, In your project, according to the load-bearing system and existing structure information, reinforcement is laid on continuous foundations according to the design moments, that is, as necessary. Project notes; -According to Article 3.3.1.1a.) of TBDY2018, it would be appropriate not to accept the basement as rigid. Do not mark the RijitX and RijitY columns on the basement floor in the Floor General Settings dialog. In this case, the basic design moments and accordingly the need for longitudinal reinforcement area are reduced. - In some continuous foundations, it is seen that the ratio of foundation height to free span is less than 1/10 in geometry control. Increasing the foundation heights contributes to the reduction of foundation design moments and accordingly the need for reinforcement space. -In the General Reinforced Concrete Parameters dialog, enter the angle value >16 degrees in the "Continuously accept beams with small angle difference" line. In this case, the fundamentals of TK83 and TK82 are solved continuously. Change the viewing direction of the TK84 continuous foundation with the Change/Beam-Foundation/Determine Object Direction command. In this case, the basics of TK84 and TK78 are constantly solved. -Enter the TK82 continuous basis to include all of the S24 and S26 columns. Good work
