How to find column size ( length x breadth x Width or depth ) |      What is mean by stiffness ?  | How to find load acting on the structure ? What the loads are called dead load ? What are the loads are called as Live load?  What are the loads are lateral loads? In basically to finding the column size is little difficult. But not much, to find column size we need to follow three steps  Step : 1 - Assumption Step : 2 - Stiffness checking Step : 3 - Load acting on the structure. Assumption:-  If you are going to construct residential or commercial building, all we have to do planning ( 2D drawing),  with the help of the plan we can mark the column positioning. With the help of column position we can assume the Length x breads x depth. In column length mean Height of the column, usually we are using min 3m (10') maximum depends up on the usage. Breadth and Depth normally we can assume 200mm minimum depth as per IS code 456. We can take this are...

Advantages and disadvantages of GFRG panel and Construction method of GFRG panel

Image
GFRG (Glass Fibre Reinforced Gypsum)   panel is a construction material, It was approved by Indian government.. So do not get fear by using the material. It was tested by IIT Madras and the tested report was created by user manual. By using User manual, We can make the structural design of our own structure. The user manual available in link below click here GFRG panel made by Glass, Fibre and Gypsum . The construction material called GFRG panel  practised from Australians, then china and now India also.  In India the material were tested by BMTPC (Building Material and Technology promotion council) with the Help of IIT madras  Advantages of GFRG panel. 1. Low labour cost. (70 percentage of work were done by machines. Manufacturing process done by industrial machine and executing process were done by using earth work equipment like mobile crane. Of-course we need a labour but compare to normal RCC structure, the Labour cost is low)    2. Low material cost...
