With respect to an alteration of a building or a facility, something that has little likelihood of being accomplished because existing structural conditions would require removing or altering a load-bearing member that is an essential part of the structural frame; or because other existing physical or site constraints prohibit modification or addition of elements, spaces, or features that are in full and strict compliance with the minimum requirements.
Annealed glass that has been cut to size, heated up to 620o C then cooled quickly with jets of cold air. The outer layer contracts and solidifies before the inner core, and when the inside eventually cools and shrinks, it pulls on the outer layer resulting in a very stable and strong piece of glass up to 5 times stronger than annealed glass. However there is a lot of energy stored in the glass, contained by the outer layer, such then if and when the outer layer does fail there is a spectacular explosion or shattering of the glass.

Two-way rigid framework
Two-way rigid framework are made up of two planes of rigid frames intersecting at right angles using common columns at the intersections. This type of framework resists lateral forces in both planes by frame action without the need for any stabilizing elements. All the beam to column connections must therefore be of a rigid type. The columns may need to have approximately equal stiffness in both directions, so that boxed or tubular columns may be employed due to their high stiffness about both principal axes. Under the action of lateral forces, there is always some sway as a result of the elastic deformation of the framework.The main advantage of the two-way rigid framing system is in the complete freedom in the planning it offers. Also the reduction in the sizes of the floor beams due to the end rigid fixings. On the negative side is the need for more costly rigid connections and the extra mass required in the column sizes.
