This question makes no sense. A 90 lb load per sq. ft. refers to an area. To calculate the stresses on beams supporting an area you have to know the spacing between adjacent beams as well as the span.
p.s. This qn when fixed belongs in mechanical engineering.
150*150*10thk h beam weight per meter
it is about 35 :)
It varies between companies, and is also affected by the value of the load itself.
freight rate per mile usually mean a full truck load or full pup load. this is the amount of money the trucking company will charge you for the load based on mileage from the pick up location to the delivery location. You can get current national per mile rates for free at www.fairtran.com/rates.aspx
"per square metre" is not a measure of size.
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati
first you need to calculate the load on the entire floor. Different uses mean different loads, you look that up in the building code. Then you calculate how much of the floor is held up by the beam. Then you look up what size of beam to use for the number of pounds per lineal foot. For 1 or 2 family homes you can have a lumber yard do this for you. For commercial construction it has to be done by an architect or an engineer.
A uniformly distributed load is one which the load is spread evenly across the full length of the beam (i.e. there is equal loading per unit length of the beam).
Stiffness is defined as the ratio of load per unit deformation.
It depends on the size of the H beam
The answer to this question is too complex to describe here. There are too many factors which are not specified in the question, such as load in pounds per linear foot, spacing of the 4X12 joists, as well as grade and species of lumber.
Yes there is. Good luck trying to obtain one. It is a pretty closely guarded chart. Apparently engineers feel they need to give that information out. At $120 per hour. You might be able to get one in dealing with a motorized chain lift company. That is how I got mine.

Stiffness is defined as the ratio of load per unit deformation.
Yield momnet; or the moment at which the concrete beam will fail due to bending can be calculated by:M= (W*L*L)/8Where M= Yield MomentW= weight on beam (Kn usually)L= Span of Beam (M usually)M will be in :Kn per morKn/mhope This helps.
Moment is the product of force and distance. as the distance of the section of the beam varies form the load the moment occuring at different section are different leading to increase in moment with increase in distance of the section from the load. In contineous or fixed structure the support moments are distributed among the members meeting at the joint as per their relative stiffness so the distribution of support moment is not uniform. Note:- relative stiffness the ratio of moment of inertia to the effective length of the member.
