Title: THERMAL STRESSES IN CONCRETE BRIDGE SUPERSTRUCTURES UNDER SUMMER CONDITIONS
Accession Number: 00128545
Record Type: Component
Availability: Find a library where document is available Abstract: Current design practice for deep concrete bridge superstructures generally ignores the influence of the diurnal heating cycle on the flexural response of members and instead, considers mean temperature effects. A 1-demensional heat-flow analysis is used to study the flexural deformations and stresses that are developed in deep concrete sections as a result of a typical summer heating cycle. Both nonlinear temperature and stress distributions are observed, and nonlinearity increases with member depth. An analysis of 2 typical continous concrete structures indicates stresses exceeding those associated with live load and amounting to 40 percent of the allowable area possible for concrete structures having a depth of more than 4 ft (1.22 m).
