USE NSCP $2015$

Problem $1$: A reinforced concrete beam is $250$ mm wide with an effective depth of $400$ mm $.$ Use $fc=21$MPa and $fy=275$MPa. The section is

reinforced with $4-25mm$ bars. Use $U=1\mathrm{.}2DL+1\mathrm{.}6LL.$

a$.$ Determine the nominal flexural strength.

b$.$ Calculate the safe service live load moment if the service moment from total dead load is $96kN-m.$

c$.$ If the beam is $5$ m long with a moment from total dead load of $96$ kN $-$m$.$ find the maximum moving concentrated service live load that can be

supported by the beam.
