Sketch a G+1 residential plan according to Vaastu Shastra and Calculation of Loads as per IS code
Aim: Sketch and calculate the Dead load and live load for G+1 building as per vasthu shastra.
Introduction:
Vastu shastra is a sanskrit word which means " Science of architecture " (or) Vastu shastra ia an ancient vedic indian science of architecture, it contains many design ideas such as space arrangement, measurements and layout. Vastu shastra also called as the Yoga of designs and its guidelines are taken from the knowledge of ancient indian text " Vastu vidya".
Buildings which are constructed using principles of vastu are said to have healthier living space and best energy balance. The main idea behind vastu is to intregrated with spiritual beliefs and nature. Vastu shastra concept is based on combining scientifically the basic five elements - earth, water, fire, air and sky which creats a pleasant setting. Vastu shastra principles boosts health, wealth, prosperity and energy and making the working or living space enlightened.

Balcony live load= 1.5kN/m2
Live load= 2.5x8.5x9.5= 202kN
Live load from balcony= (4.5x2+1x9.5)x1.5= 27.75kN
Total LL from first floor= 202+27.75= 230kN
Total Live load from first floor= 230kN
Live load from ground floor:
Assume LL= 2.5kN/m2
