Objective Question
Find the effective length of an isolated cantilever RCC beam as per IS 456:2000, where the length from the
free end to the face of support is 1 m, the effective depth of the beam is 400 mm and the width of support is
300 mm.
Find the effective length of an isolated cantilever RCC beam as per IS 456:2000, where the length from the
free end to the face of support is 1 m, the effective depth of the beam is 400 mm and the width of support is
300 mm.
Given / दिया गया है:
Clear length / स्पष्ट लंबाई, L=1 m
Effective depth / प्रभावी गहराई, d=400 mm=0.4 m
Width of support / आलंब की चौड़ाई, b=300 mm=0.3 m
As per IS 456 : 2000, Clause 22.2(c) / IS 456 : 2000 के खंड 22.2 (c) के अनुसार:
For an isolated cantilever beam, the effective length shall be taken as the length from the face of
the support to the free end plus half the effective depth, except where the cantilever forms the
end of a continuous beam.
एक पृथक कैंटिलीवर बीम की प्रभावी लंबाई, आलंब के फलक से मुक्त सिरे तक की लंबाई तथा प्रभावी गहराई के आधे के
योग के बराबर ली जाती है, बशर्ते वह सतत बीम का अंतिम भाग न हो।
