Ching in reading seven talks about masonry arches, masonry lintels, wood beams, wood joists, wood sub-floor/decking, wood plank/beams, steel beams, steel open-web joists, metal decking, and reinforced concrete beam.Masonry arches utilize the compression strength of brick and stone to span openings by transforming
the vertical forces of a supported load into inclined components. Masonry lintel where describe in many different forms of diagrams. wood in general was also described in the way they are used and positioned. Steel overall was explained in its constructional way in use. Metal decking is corrugated to increase its stiffness and spanning capability. The last thing discussed was Reinforce Concrete Beams. Ching explains how they are designed to act together with
longitudinal and web reinforcement in resisting applied forces.
