This scrapbook of brick chimney design materials was assembled by a state-owned, locally administered engineering company based in Liaoning, and provides numerous notes, reports, drawings, diagrams, and calculations testifying to the challenges presented by new types of material production and construction practices being introduced into China by the late 1950s. Determining the optimal dimensions of structures like chimneys was vital to ensuring they would perform as expected, particularly in relation to variables such as site-specific load-bearing capacities and wind flow.
