Building History

The Sloane Building collapsed during the fires that swept San Francisco, CA, following the San Francisco Earthquake 04/18/1906. The US Geological Survey published a book summarizing the structural damage in the city after the quake and fire, and said this of the Sloane Building: "The seven-story Sloane Building, on Post street between Grant and Kearney streets, had bearing walls of terra cotta, brick and terra-cotta trimmings, and a framework of cast-iron columns and steel beams and girders. The partitions and fireproofing were of expanded metal, plastered, and the floors were of concrete, reenforced with expanded metal. All columns except those in basement were fireproofed with expanded metal, plastered. There is every indication of a very hot fire in the basement, which buckled several of these unprotected columns, causing a collapse in the central portion of the building." (See Grove Karl Gilbert, Richard Lewis Montgomery, John Stephen Sewell, and Frank Soulé, The San Francisco Earthquake and Fire of April 18, 1906 and Their Effects on Structures and Structural Materials, [Washington, DC: Government Printing Office, 1907], p. 47.)
