CADD OF RETAINING WALLS USING VISUAL BASIC

Abstract

Retaining walls are very important and widely used structural elements especially in construction in hilly region for both buildings and highways. Hence ' designing retaining walls with adequate safety and economy deserves attention. Experience has shown many advantages using computer programs. A great deal of valuable time in designing and analyzing the retaining wall can be saved. Graphic package reduces the drafting time and the results in the form of graphics give the designer better feel of design. In the present dissertation an attempt has been made towards the development of a user-friendly interactive program for design and drafting of reinforced concrete inclined retaining wall and gravity wall. In this program ease and flexibility is available in window based commercial packages on today's comters has given prime importance while developing the program. Earth pressure due to backfill, earth quake and water table has been taken into account as per IS: 1893-1984. The design is carried out on cracked, uncracked and no seepage analysis as per IS: 3370 (part II) for water on toe side and working stress method is user for design as per IS: 456-2000. The package fulfills the requirement of the day and satisfies the need of the user.
