Optimum Design Of Anchor Block Suppoting Penstock

Abstract

Anchor Blocks are the massive structure which supports the large diameter pipe. The massiveness of such blocks make them considerably costly and particularly in case of long penstocks where a number of such bends are needed, the total cost can form a substantial portion of the total penstock budget, so it is required to make optimized Anchor Block. This thesis is an attempt to understand how to optimize the shape and size of Anchor Block by fulfilling all the requirements required to stabilize it. Analysis and Design of anchor block was carried out for five different types of bend, namely, vertical (concave & convex), horizontal and combined bends (concave & convex) at different location along the length of penstock having different location with optimized shape. Also parametric study was undertaken to understand the influence of different parameters on the shape of Anchor Block. Software based on VB platform was also developed for user (any) to quickly analyze and design the anchor block. Software also, carry out structural reinforcement detailing for all types of anchor block. The results obtained from a developed software were validated for input data’s from L & T, chhani, Baroda.
