Seismic Forces—Regular Structures
"Regular structures do much better in earthquakes..."
Buildings in previous chapters were regular.
"Regular structures...
Honor Bilt Modern Homes (see pdf)...have no significant physical or structural irregularities in either plan view or elevation.
...the plan is essentially rectangular.
...the mass is reasonably uniform over the height.
...shearwalls in each upper story must be located directly over the shearwalls in each lower story."
"From 1908–1940, Sears, Roebuck and Company sold more than 100,000 homes through their mail-order Modern Homes program. A few weeks after the customer selected a home and placed the order, two railway boxcars containing 30,000 pieces of house – everything from doorknobs and carved staircases to varnish and roof shingles – would arrive at the nearest train depot." source
