TITLE: ANALYSIS OF Reinforced Concrete Beams (SERVICEABILITY REQUIREMENTS).
PROBLEM:
Check the serviceability requirements in terms of deflections. Assume concrete weighs 23.5
KN/m³, fy = 414 MPa, and f'c = 28 MPa.
PLI = 133 kN
PLI = 89 kN
WDL = 29 KN/m + Selfweight of beam
1.2 m
1.2 m
2.4 m
78 тm
4 - #32
800 тm
722 тm
400 тm
COMPUTATION:
Required:
1. Check serviceability requirement using
480
(span length) as the allowable.
a.
Short term deflection
b. Long term deflection assuming 50 % of liveload is continuously applied for 4 years.
