Design continuous slab and beam

[oranda]

When analysing continuous slab and beams, do you design them as simply supported or do you incoporate columns (below and above) at the supports?

 

[Evank]

The way they will be placed has a bearing on this matter. If all will be "poured" together that makes them monothilic and they can be designed as continuous. But if not then the design depends on your treatment of the places where pour joints do occur. At those points you need to be assured that the steel is continuous via lapping, and the joint is made non-slip. The assemblage has to be treated and designed as you want it to work.
