Steel deck is made by cold forming structural grade sheet steel into a repeating pattern of parallel ribs. The strength and stiffness of the panels are a result of the shape of the ribs and the mate-rial properties of the steel. Deck lengths can be varied to suit job conditions but, because of shipping considerations, are usually less than 40'.


3.3 Considerable care must be used to compare the results of different determinations of the cold crushing strength or modulus of rupture. The specimen size and shape, the nature of the specimen faces (that is, as-formed, sawed, or ground), the orientation of those faces during testing, the loading geometry, and the rate of load application may all significantly affect the numerical results ...

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be …


Carlson's major strength is the breadth of our technical laboratory capabilities. Our laboratories are capable of testing and evaluating a wide variety of construction materials, ranging from common concrete and masonry samples to unique, proprietary, or experimental materials or components.


The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.
