What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
12 inch
250 feet
16mm dia weight for running feet
If I am reading the question correctly, a load bearing wall was removed and replaced with a beam? Clear span, no post in the middle? If cracks are appearing, the beam that was used was not big enough. For any space of 8 feet or more, 2x12 and plywood should be used for the beam or an engineered truss used.
The maximum height depends on many factors like the snow load, the wind load, the size of the building, etc. Typically residential post and beam frames can be three stories or more. Commercial frames can go 60 or 70 feet or higher.
38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.
Use a steel beam.. That would be code.. steel w10x15 (50ksi) I beam.
With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
Possibly, but you haven't mentioned thickness of the steel -8 x 24 is not enough info for that calculation.
There are a lot of considerations to be taken into account for sizing steel shapes, especially for a residential home. For instance, what are the load imposed upon the beam? How will the beam be supported? What environment will the beam sit in (i.e. high humidity, moisture, vibration)? A licensed professional engineer or architect in your state can better answer this question.
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
well a low beam can be from nothing to 1 foot high a medium beam is 2 and a half feet high and a standard high beam is 3 and a half feet high
250 Feet
That depends on how heavy it is. Steel beams are measured by height and width and weight-per-length As an example A beam you describe as measured in the UK could be 200mm X 100mm X 30kg/m 12 feet is approx 4m so total beam weight 120kg. This is just an example and it all depends on the unit weight. If you measure the thickness of the steel then look up steel tables online you should get a pretty good idea.

A Balance beam is 16 feet long and 4.5 inches in width and height varies.
