Abstract
The report is intended to summarize existing information about the seismic performance of tilt-up construction. The scope of the report is limited to traditional, tilt-up structures in which concrete wall panels are cast horizontally. No attempt is made to interpret the response of tilt-up frame structures. The report is divided into seven chapters. Chapter 2 describes the influence of construction techniques on the design of tilt-up structures. Design considerations for the wall panels, the roof diaphragm, and the critical connections used in tilt-up construction are discussed in Chapter 3. In Chapter 4, the results of previous experimental tests of tilt-up wall panels and roof diaphragms, and previous analytical studies are summarized. Acceleraton histories recorded during recent earthquakes measured in three tilt-up buildings in California are evaluated in Chapter 5. Chapter 6 summarizes the damage observed in tilt-up structures following the 1964 Alaska, the 1971 San Fernando, the 1987 Whittier Narrows, and the 1989 Loma Prieta earthquakes. Results are summarized in Chapter 7.
