For BIS Use Only Doc: CED38 (7811)P June 2011 BUREAU OF INDIAN STANDARDS Preliminary Draft CRITERIA FOR DESIGN OF RCC STAGING FOR OVERHEAD WATER TANKS (First Revision of IS 11682) Special Structures Sectional Committee, CED 38 FOREWORD (Formal clauses of the standard will be added later.) This standard was first published in 1985. This first revision was taken up to keep abreast with the rapid developments in design and construction fields, and to bring further modifications in the light of experience gained. Liquid tanks are important public utility and industrial structures. Specifications, the design and construction method in reinforced concrete are influenced by the prevailing construction practices, the physical properties of the material and the environmental conditions. Based on the experience in design and construction of staging of elevated tanks, necessity of revising the standard was felt (see Commentary, E-1). While the common methods of design have been covered in this standard code, design of structures of special forms or in unusual circumstances should be left to the judgment of the Design Engineer and in such cases special systems of design construction may be permitted on production of satisfactory evidence regarding their adequacy and safety by analysis or test or by both. If applicable at a particular location dust load should be accounted on roofs. In this standard it is assumed that the design of liquid tank and staging is entrusted to the qualified engineer knowledgeable with the current engineering practice related
