Abstract: The layout planning is a part of urban development it includes planning of residential houses, commercial complexes, service roads, primary health centers, school…& other amenities sewerage system for whole layout (includes treatment, sewer line, storm water drains), water distribution system. This project includes design& estimation of residential building in plot of layout planned. Designing involves identifying the loads which act upon a structure and the forces and stresses which arise within that structure due to those loads, perform analysis to get moments and shear forces on different elements of the structure and then design the structure for ultimate loads and moments. The loads can be self-weight of the structures, other dead loads, live loads, moving (wheel) loads, wind load, earthquake load, load from temperature change etc. Estimation includes finding the quantities of materials required for the construction of the structure and requirements of labor etc., finally determining the overall cost of the structure before execution of work by using Auto cad. Structural engineers are facing the challenge of striving for the most efficient and economical design with accuracy in solution, while ensuring that the final design of a building must be serviceable for its intended function over its design lifetime. This project attempts to understand the structural behavior of various components in the multi-storied building. Analysis, designing and estimation of multi-storied building has been taken up for Basement+G+2 Building, thereby depending on the suitability of plan, layout of beams and positions of columns are fixed. Dead loads are calculated based on material properties and live loads are considered according to the code IS875-part 2, footings are designed based on safe bearing capacity of soil. For the design of columns and beams frame analysis is done by limit state method to know the moments they are acted upon. Slab designing is done depending upon the type of slab (one way or two way), end conditions and the loading. From the slabs the loads are transferred to the beams, thereafter the loads from the beams are taken up by the columns and then to footing finally the section is checked for the components manually and for the post analysis of structure, maximum shear force, bending moment and maximum story displacement are computed. The quantitative estimation has been worked out. All the drafting was done using Auto cad.
