Numerical example on design of open well stairs

[@halalmeatshophk]

Why is the column and beam support not put in the equations for these open well stairs?

[@civildocuments6740]

Sir, for span BC at the ends there is no support given in the question, then why are we taking the effective length as 4.5 m ??

[@rabindra_maharjan]

there are wall support (i.e 300/2+1400+1400+1400+300/2)

@@rabindra_maharjan Thank you sir, may i ask another question, is it possible to design the span BC without wall supports , if yes then what will be the effective length ??
