Study on Steel Content Estimation of Reinforced Concrete Rectangular Pool Wall

Table 4

Rebar configuration and steel content selected by the principle of minimizing reinforcement area.

Wall thickness	250	300	350	400	450	500	550	600	750	800
Actual rebar configuration	φ25@100	φ22@100	φ20@100	φ22@125	φ20@125	φ25@200	φ16@100	φ14@100	φ14@100	φ16@125
Actual reinforcement area	4910	3800	3140	3040	2512	2455	2010	1540		1608
Steel content	1.96%	1.27%	0.90%	0.76%	0.56%	0.49%	0.37%	0.26%	0.21%	0.20%
