Distribution Steel
Why we provide distribution steel in one way slab?
What is role of distribution steel in one way slab?vipkolon
- May 24th, 2010
Distribution steel is provided for countering stresses generated due to change in temperature and shrinkage in concrete (caused due to hydration reaction) in lateral direction. Absence of same will generate stresses and consequently cracks.

Angles and Angle Pairs
How are angles and angle pairs used in civil engineering?
sappy_shail
- Nov 23rd, 2009
Angles can be used to make trusses, hold fasts etc and angle pairs for making 'T' section or square hollow section. However you can use it with your ingenuity for many things viz chairs, end stubs to reduse Anchorage length, door frame, shutterings, in lap weldings, make sharp edges.

What is the differance between Load and Force?
paulgomes
- Oct 9th, 2009
Load = mass x gravity this vertical and directed by gravity. towards the earth center. Force on the other hand is free and can have any direction.
