In as much as possible, general principles of analysis. DESIGN METHODSThe British Codes applicable for the design of concrete water retaining structures are BS8. Autocad 2000 Full Crack Membrane' title='Autocad 2000 Full Crack Membrane' />BS5. The. designs are usually carried out either based on Limit State or Elastic State, up to the designing engineer or. Codes used. Limit State Design. This is based on Ultimate Serviceability design criteria, where the structural strength stability. Ultimate Loads, using factor of safety for Loadings, such as 1. Life Load and 1. 4 for Dead. Load while Serviceability is simply based on limiting crack widths of concrete sections in contact with water or. The important analysis here is ensuring that the final crack widths would not exceed the maximum permissible. BS5. 33. 7 codes, and to ensure proper construction and movement joints. The British Standard Codes allow for two options in the analysis 1 by limiting Maximum Allowable Surface. Crack Widths due to bending and tensile forces, and 2 a Deemed to Satisfy criteria where the Maximum Service. Stresses in the rebars are intentionally lowered to ensure cracks will not exceed permissible values. It is up to. the engineer to choose whichever options is preferred. Elastic Design. This is based on Working Loads and Permissible Stresses in both concrete and steel rebars, and assuming a. The design approach is relatively simple and generally favoured by most. Calculations are performed to suit two basic Criteria Strength and Resistance to Cracks. Strength of. the structure is calculated assuming the concrete section is cracked, and by reducing the permissible stresses in. Calculations for Resistance to Cracking in done by limiting the tensile stresses in concrete sections based on an. Working Loads. Shape of Tanks. Concrete Water Storage Tank is normally shaped as Square or Rectangular or Circular on plan. It can be elevated. The choice depends on the engineer. Sizes can vary in lengths, widths and height, or diameters. Game Prime World Defenders Full Throttle. Autocad 2000 Full Crack Membranes' title='Autocad 2000 Full Crack Membranes' />Internally, the tank can have several compartments for purpose. The roof can be reinforced concrete slabs or simply metal roofing. The walls are usually reinforced concrete. The base is also reinforced slabs. For Square or Rectangular shape, the design is normally carried out simply as a Retaining Wall, with water on. Design of Roofs. The design of roof slab is normally carried out as one way or two way slabs, supported by RC beams. In some. cases, use of flat slabs with intermediate columns are also used. The main criteria for design will be having. Generally, the undersigned will be designed for permanently moist conditions, while externally for worst weather. Design of Walls. The normal design approach is by assuming the walls and base acts together like a Retaining Wall, with the inner. The method of design is as outlined above. Design of Base slabs. This will depend on whether the tank is elevated, resting on ground level or buried underground.

This methods described below will outline in brief the procedures for construction of the RC Reservoir. External Infrastructure interfacing works are excluded and assumed to be ongoing or constructed. SURVEY SETTING OUT1. A licensed Surveyor will be employed to setout the vertical horizontal control levels datum. Thereafter, site surveyors engineers will continuously check for accuracy, and adjustments will be made. Temporary Bench Marks Controls will be set out around the Tank. PREPARATION OF FOUNDATION1. It is understood that the existing ground strata consist of weathered shale. The existing ground, surrounding the tank extending not more than 3. Foundation Levels Overall Ground area 2. I3. 7. 0M I 2. Column Footing area 2. I3. 5. 0M I 2. M 4. Retaining Wall Footing 2.

Foundation Level using mass. Where mass concrete is used, the 5. Where backfilling is sand or fine granular materials, the backfill must be compacted using a minimum of 6. Backfilling with sand fine granular materials compaction should be carried out in dry weather. Where. weather doe not permit, mass concrete grade 2. Backfilled surface, shall be protected. Any voids not possible to be compacted by rollers or hand compactor, will be filled with mass concrete grade. Where sandgranularblinding layer is formed, a single layer of polythene sheet shall be laid level before. Foundation Level ready to receive Base Slab. Curing will not be required for mass concrete, other than protection from direct rain via one layer polythene. Foundation Levels will be re checked by Licensed Surveyor for Level Accuracy. CONSTRUCTION OF GROUND SLABS. WALL COLUMN FOUNDATIONS1. Internal ground slabs will be constructed in 1. The sides consist of 1. The outer panels made up of foundations of retaining walls, will be constructed in 1. Formwork. 1. Plywood Formwork will be placed according to panels in alternate sequence, such that when one panel sets. Bitumen will be used to coat. Formwork as release agent. Formwork maybe reused twice depending on conditions. For curved sides, thinner plywood formwork in single layer will be used. They will be bent slightly to suit. Where bending cannot be achieved without cracking the. Rebars. 1. One layer mesh reinforcement DA8 will be placed on Top of slab with 5. The mesh will be bent at joint slightly if equipment permits, or if not practical, additional bent lap.
