ABSTRACT
DESIGN OF SLABS 12.1 INTRODUCTION It is generally felt that for spans greater than about 6.0 m, post-tensioned slabs start to become cost effective. The vast majority of post-tensioned slabs use unbonded tendons purely because they considerably reduce the construction cost. Some of the significant advantages of post-tensioned slabs compared with reinforced concrete slabs are:
• Longer spans with fewer columns leading to flexibility in the positioning of partitions.
