8 story structural drawing with plan dwg
The main objective of this project is to analyze and design a multi-story building (2d-dimensional reinforce concrete frame); the design of reinforced concrete slabs; beams; columns; footings and staircase were made by hand calculations according to euto- code and compare the results by using autocad. in order to design; it is important to first obtain the plan of the particular building that is; positioning of the particular rooms (drawing room; bed room; kitchen toilet etc.) such that they serve their respective purpose and also suiting to the requirement and comfort of the inhabitants an office building were used with reinforced concrete frame consists of three floors where the maximum area of floor =(21.9*40.9) m2. each floor consists of twelve offices. we used autocad programs to complete the architectural design; the design process of structural planning and design requires not only imagination and conceptual thinking but also sound knowledge of science of structural engineering besides the knowledge of practical aspects; such as recent design codes; bye laws; backed up by ample experience; intuition and judgment. the purpose of standards is to ensure and enhance the safety; keeping careful balance between economy and safety. for designing of columns and beams; it is necessary to know the moments they are subjected to. 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. thereafter; the loads (mainly shear) from the beams are taken by the columns. finally; the sections must be checked for all the four components with regard to strength and serviceability. analysis of multi-storey building frames involves lot of complications and tedious calculations by conventional methods by hand. to carry out such analysis is a time consuming task. this project is deal with many computer programs to help us to complete the work. an excel programs were designed to calculate the moments in slabs using method two with interpolations to factors and loads in beams with moments and design section and reinforcement. this program is more effective for analysis the two way slab; by inter a few numbers of variables that related with type of slab and the dimension of beam and columns and the expected applied load. then the program calculated the combination load that will be applied on the frame; and then check the thickness of slab with the limitation of shear. then the program divided the slab to several frame in the two directions vertical and horizontal; and calculate the details moment for each part of span; and then calculate the required area of steel for each moment. this study is divided into seventh chapters: ? the first chapter presents the introduction about multi-story buildings and slabs; beams; columns; footing etc.. ? the second chapter contains types of load on structure. ? the third chapter presents the design calculations of slab and drawing of building. ? the forth chapter presents the design calculations of floor beam. ? the fifth chapter presents the design calculations of columns and footing. ? the sixth chapter presents the design calculations of staircase. ? the seventh chapters present the conclusions and recommendations of this study
