Continuous Beam Design
(OP)
Hi there, i would like to ask how to design different level of beams (or) different size beam as continuous beam?
For example:
1. Span 1 Span 2 Span 3
250 x 450 250 x 600 250 x 750 (beam size)
2. Span 1 Span 2 Span 3
+450 +400 +350 (beam level)
Example 1 is beams with different sizes (bottom level of beam is same)
Example 2 is beams with same sizes but different level.
Thank you =)

RE: Continuous Beam Design
When detailing the joints, the effects of the disposed rebar must be inspected to further ensure (usually by strut and tie) that not unbearable/adverse effect develops.
When you have RC column supports monolithic to the beams you may have facilitated the transfer through its existence, then avoid transition corbels. The corbels when used and if needed more properly should be accounting when analyzing the structure, but sometimes as non consequential their presence is ignored in analyses.

For beam span 1, 2 and 3 use the +ve design moment for the bottom and determine the area of steel required. You may want to keep some common bars.
For the negative moment between span 1 and 2 use the smaller depth to determine the area of steel. For the negative moment between span 2 and 3, use the area of steel determined for span 2.
Check for deflection and shear and you're done like a dinner...
I don't understand what your second beam is...
