1. Plane sections normal to axis remain plane after bending. This implies that strain is
proportional to the distance from neutral axis.
2. Maximum strain in concrete of compression zone at failure is 0.0035 in bending
3. Tensile strength of concrete is ignored.
4. The stress-strain curve for the concrete in compression may be assumed to be
rectangle, trapezium, parabola or any other shape which results in prediction of
strength in substantial agreement with test results.

What is a un-factored load and a factored load?
Oh honey, let me break it down for you. A un-factored load is like a wild horse running free, it's the load acting on a structure without any safety factors applied. Now, a factored load is when we slap on those safety factors to account for uncertainties and make sure that structure can handle whatever life throws at it. So, in a nutshell, un-factored load is the raw deal, while factored load is the safety-net version.
What is tensile load?
Think of a tensile load as a "pulling" force. A tensile load is the only type of load that can be taken by a rope, for instance.
What is the difference between live load and roof live load?
Live load Both are the same Live load is all the live loads which can be consider as variable load. Roof live load This is limited to few categories. man who climbed on to the roof can be consider as roof live load.
Define - No load bearing wall?
A wall bearing no load.
What is the basic difference between buckling load and critical load?
buckle means bending
