Abstract:

The deflection calculation of slender, lightly reinforced, concrete members is investigated. It is observed that the different available calculation methods produce different deflection results. The reasons for the irregular results are investigated. The various deflection prediction methods include empirical hand calculation methods as presented in SABS 0100-1, the Eurocode2, and the ACI 318. Comparisons are also made with the finite element method using a commercial software package. It is shown that deflection calculations do not consider construction and post construction conditions, often resulting in non durable and non sustainable structures.
