Response of Reinforced Concrete Structures to Aircraft ...
predict damage to reinforced concrete structures caused by an aircraft crash impact. An aircraft crash impact is a short duration dynamic load that could involve very large deformations and damage to both the reinforced concrete structure and the aircraft itself. Therefore, simulation of aircrash impact is computationally challenging.

How to Build a Concrete Foundation: 7 Steps (with Pictures)
If you are constructing a slab, the minimum thickness of concrete slab is 100 mm but the preferred thickness is 150 mm. The thickness (dimensions) of reinforced concrete columns and beams varies as it depends upon the load a building is designed to carry. The Plain Cement Concrete laid before laying the foundation is usually 75 mm.

(Reapproved 2006) REINFORCEMENT FOR CONCRETE— …
2.2—Reinforced concrete Plain concrete (Fig. 2.2) has compressive strength—the ability to resist crushing loads; however, its tensile strength is only about 10% of its compressive strength. Its tensile strength is so low that it is nearly disregarded in design of most concrete structures. Reinforced concrete is a combination of adequate

How to Reinforce Concrete - wikiHow
For your concrete to be adequately reinforced, the rebar needs to be positioned closer to the center of your slab rather than the bottom of it. Use chairs that will position your rebar about in the middle of your slab. For example, if you plan to pour 4 inches (10 cm) of concrete, use chairs that are 2 inches (5.1 cm) high. 5

How to Break Up Concrete by Hand
Dig out the soil, gravel, or other material from under the concrete, using a shovel and a pickax or mattock. Dig about 1 foot inward from the slab's edge, making a gap of 1 inch or so; the void does not need to be deep. A pickax or mattock is handy for cutting through roots, breaking up rock or shale, and scraping material out from under the slab.
