For continuous floor slabs carried on beams, the ratio of the end span length to the intermediate span length is maintained at____________________?

Select your answer for: For continuous floor slabs carried on beams, the ratio of the end span length to the intermediate span length is maintained at____________________?
Show answer

Answer: D. 0.9

Explanation

For continuous floor slabs carried on beams, standard empirical ratios maintain the end span length at zero point nine times the intermediate span length. This dimensional proportioning accounts for differing bending moment distributions between end spans and interior spans. Balancing span lengths helps standardize reinforcement detailing and ensures uniform structural performance across multi bay floors. Continuous floor slabs extend over three or more supports, creating negative and positive bending moment regions across spans. End spans experience different boundary restraint conditions compared to fully continuous interior span segments. Empirical coefficients in building codes simplify the analysis of continuous beam and slab floor systems.

Zero point six represents an excessively short end span ratio that does not align with standard continuous floor design practice. Zero point seven is lower than the recommended empirical proportion for balancing moments in continuous concrete floor slabs. Zero point eight provides a shorter end span than the standard zero point nine ratio typically specified in building codes.
