Evaluation of ISDS software

Abstract

<p>When we compare the results of the analyses from ISDS and FAP, we fmd that the results compare very well, with almost negligible percentage difference.</p> <p> The results from the reinforced concrete design method and the design using ISDS also compare very well. But, ISDS does not specify a few details such as:</p> <p>1. How much positive moment steel in a beam or a slab must be extended into the supports and up to what distance? 2. Anchorage requirements (in the form of hooks) for negative moment reinforcement in a beam, slab or a shear wall. It simply mentions if anchorage is required or not. 3. What amount of minimum shear reinforcement is required for various structural elements such as beams, columns, and slabs etc? 4. Size and spacing of ties in a column. S. Cover for main and secondary (ties) reinforcing bars in various structural elements. 6. Class of splice when required.</p>
