ANALYSIS AND DESIGN OF PUMP HOUSE
Abstract
Structural design is the primary aspect of civil engineering. The very basis of construction of any pump houses, residential house or dams, bridges, culverts, canals etc. is designing. Structural engineering has existed since humans first started to construct their own structures.
The foremost basic in structural engineering is the design of simple basic components and members of a pump house viz., Slabs, Beams, Columns, Wall and Footings. In order to design them, it is important to first obtain the general arrangement drawing of the particular structure that is, positioning of the particular pumps (control panel room, office room, battery room, store room, outlet pipe, suction and delivery pipes etc.) such that they serve their respective purpose and also suiting to the requirement and comfort of the inhabitants. Thereby depending on the suitability; plan layout of beams and the position of columns are fixed. Thereafter, the loads are calculated namely the dead loads, which depend on the unit weight of the materials used (concrete, brick) and the live loads, which according to the code IS: 875-1987 is around 2 kN/m2.
Once the loads are obtained, the component takes the load first i.e. the slabs can be designed. Designing of slabs depends upon whether it is a one-way or a two-way slab, the end conditions and the loading. From the slabs, the loads are transferred to the beam. The loads coming from the slabs onto the beam may be trapezoidal or triangular. Depending on this, the beam may be designed. Thereafter, the loads (mainly shear) from the beams are taken by the columns. For designing columns, it is necessary to know the moments they are subjected to. For this purpose, frame analysis is done by STAAD PRO SOFTWARE. After this, the designing of columns is taken up depending on end conditions, moments, eccentricity and if it is a short or slender column. Most of the columns designed in this mini project were considered to be axially loaded with uniaxial bending. Column and Beam Results are taken from ARC BDS Software. Finally, the footings are designed based on the loading from the column and also the soil bearing capacity value for that particular area. Most importantly, the sections must be checked for all the four components with regard to strength and serviceability.
Overall, the concepts and procedures of designing the basic components of a pumping station are described. Apart from that, the GAD of the structure with regard to appropriate directions for the respective rooms, choosing position of beams and columns are also properly explained.
