L-box test – Most extreme size of coarse total was kept as 16 mm so as to abstain from blocking impact in the L-box.The hole between the rebars was 35 mm. The L-box proportion for the blends was over 0.6. U-box test – The resultant difference in the level of concrete in two chambers lies in the range of

Gregory Deierlein‚ Stanford University; Jerome F. Hajjar‚ Northeastern University For decades‚ the goal of seismic engineers has seemed straightforward: Prevent building collapse. And so they add steel braces to a skyscraper’s skeleton or beefier rebar to concrete shear walls. After absorbing the brunt of seismic shaking‚ however‚ the compromised structures often must be demolished. “The building‚ in a sense‚ sacrifices itself to save the occupants‚” says Gregory Deierlein‚ a Stanford University

Using proper fall protection on anything that exposes you to a fall of 6 feet or more. (exception is when proper use of an A frame step ladder is used) • Scaffolding needs to be inspected daily by the competent person. • Use proper caps for exposed rebar. (Must have steel plate imbedded inside the plastic cap) • All piers and excavations are required to have a 6 foot perimeter around the hole/excavation to prevent objects from falling inside the hole. • Be cautious when doing work where one is exposed

Taking a look at the brochure and website of Cook ’s nuclear station‚ one would be amazed to see all the precautionary steps taken to protect the nuclear reactor that is enclosed in a 3 ½ ft thick concrete wall reinforced with three layers of steel rebar in a reactor house that is heavily guarded by security personal with guns www.cookinfo.com). The brochure even includes an explanation of the not so foreseeable disaster if a plane crashed into the reactor house and how there is “very few combustible

Although bottle walls can be constructed in many different ways‚ they are typically made on a foundation that is set into a trench in the earth to add stability to the wall. The trench is filled with a rubble of pea gravel and then filled in with cement. Rebar can be set into the foundation to add structural integrity. Bottle walls range one bottle to two bottles thick. Primitive mixture‚ such as cob or adobe can be used as mortar to bind the bottles. It is thickly spread on the previous layer of bottles
