State the typical values for the Young's modulus of Mild Steel, Concrete, Timber and Masonry If a beam had a second moment of area (I), and was spanning a distance (L) which material property would directly influence how much it would deflect under a constant load (F)? Youngs Modulus (E) State which materials are not affected by creep and why? Masonry, generally not significant Steel, only at high temperatures State which materials are affected by creep? Timber Concr...

What is "grade" in terms for the structure? The slope of the land at the building site. What does "below grade" mean? Below the surface of the ground. What is the frost line? It marks the depth of penetration of frost into the ground. In cold climates, the frost line is normally about 4' below the grade. What are footings? Footings support and transmit the dead load and the structure's live load to the soil. Their purpose is to spread these dead and live weights ov...
