Nevertheless growing concern with inconsistencies in the specifications, and the fact that vainability in the loads and materials were not explicitly addressed, an entirely new specification was developed in the early 1990s based on load-and-resistance-factor design (LRFD). This new document is the...
It's about how accurate the load the bridge was designed for will be in 75 years. Straight from the definitions in Chapter 1 of AASHTO LRFD: Design Life - Period of time on which the statistical derivation of transient loads is based: 75 years for these Specifications. Commentary of ...
The design provisions of these Specifications employ the Load and Resistance Factor Design (LRFD) methodology. The factors have been developed from the theory of reliability based on current statistical knowledge of loads and structural performance. ...
The design provisions employ the Load and Resistance Factor Design (LRFD) methodology. They are presented in the following 14 sections: (1) Introduction; (2) General Design and Location Features; (3) Loads and Load Factors; (4) Structural Analysis and Evaluation; (5) Concrete Structures; (6...

provisions, it is urged that midspan braces be more generally recognized as primary elements of complex superstructure structural systems and thus be sized and spaced to function not only as transverse flange braces but also integrally with concrete deck slabs to distribute vehicular loads laterally. ...

In regions where the unfactored permanent loads produce compression, fatigue shall be considered only if the compressive stress is less than twice the maximum tensile live load stress resulting from the fatigue load combination specified in Table 3.4.1-1. Revise to read: In regions where...
