WebbThe upper bound governs for structures with opposite characteristics: a high base shear, either due to a short period, a low response reduction coeicient R, or a combination of the two. The upper bound represents elastic response or limited inelastic response. These limits apply to diaphragm forces calculated using either ELF or MRS analysis. Webbwalls, reinforcing steel is placed at the diaphragm level to resist the out-of-plane bending in the wall. Collectors are needed when an individual shear wall or frame in the story immediately below the diaphragm is not continuous along the diaphragm boundary (See Figure 3). This is a very common situation because shear walls are often inter-
