COMPUTER AIDED DESIGN OF MULTISTOREYED BUILDINGS

Abstract

Multistoreyed buildings are becoming an important feature of our towns and cities. Today's clients faced' with an escalation in material costs and ',rapidly increasing construction costs, demand the design phase of their jobs to be executed in shortest possible time. Since the Computer Aided Design methods effect the maximum saving in time during the stages of detailed design and preparation of reinforcement detail drawings, therefore the use of computers in design offices dealing with their construction is increasing. In structural engineering, a numper of general purpose software packages have been deveiopeu for the analysis of different types of structures including skeletal structures. So the necessity of preparation of a software package for the design of structural elements and drafting of reinforcement details in them was felt. Keeping these points in view, an attempt was made to prepare software package for the design and drafting of reinforcement details in slabs, beams and columns. The computer programs developed deal with the design of one-way slabs and two-way slabs with different end conditions and the detailing of reinforcement including calculation for quantity of materials. The program for beam deals with rectangular, T and L beams and includes reinforcement detailing i.e. it plots longitudnal section of beam and cross sections at two supports and mid span. The computer program for column can handle rectangular columns subjected to axial loading, uniaxial and biaxial bending. A computer program for drafting of a footing and column together has also been prepared. All the programs are interactive at stages where the designer would like to feed his decisions.
