In some footings inspite of unchecking the option of top steel in RCDC it gives top steel.
on increasing the size of footing in design of individual footing,the top steel is Still provided.please advice on how this can be removed.
Hi,if you are using IS 456 code, then it is mandatory to provide minimum 360sqmm steel as per clause 34.5. it is applicable to each direction on each face . So, it is applicable to top reinforcement along both the directions. refer below snap from code,So, in RCDC even if users doesn't select to provide top steel and footing depth is more than 1000mm, RCDC provides top steel.when user selects to provide top steel, it provides maximum reinforcement from user input and code clause.
The footing depth is not more than 1000mm, say for 500 mm it designs and gives top steel,
if you increase the size there should be no need of top steel right? pls advice.
Hitop steel is depend on following in RCDC,1. if footing is designed for tension in column2. footing designed with loss of contact (LOC)3.user selected the the top steel. 4. footing depth more than 1000mm (IS code)I would request you to share complete information to understand query clearly. if you share which code is used, it would become easy to answer your query. Please mention which RCDC version is used.i would always suggest user to share query with some snaps / video so that it is clear to us. Sharing RCDC file will always help us responding query properly.
