This book was released on 1979 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of two prestressed concrete composite bridge girders which were continuous over two spans are reported. Both were I-section girders with cast-in-place decks, and had spans of about 37 ft (11 m), and were approximately 1/3 scale models of structures spanning 125 ft (38 m). Each girder was constructed from three segments which were joined end-to-end by cast-in-place concrete splices. Modell was post-tensioned after erection of the girders and casting of the deck and splice concrete. The two end segments, each supported on the final abutments and on temporary supports located about 1/3 of the span from the central pier, were pretensioned for their dead loads plus the deck concrete. The central segment, which was supported on the central pier of the structure plus the two temporary supports was precast reinforced concrete, plus a small amount of pre= tensioned reinforcement. Model 2 was externally similar, but was not post-tensioned. The segments were pretensioned for the final moments, and were joined by splicing reinforcing bars which extended into the splice region. Both structures were subjected to a series of loadings to the service load, design ultimate, and high over-load levels. Both had capacities which were significantly higher than the design ultimate values. The capacities were generally predictable on the basis of flexural strength calculations, and shear did not cause major problems. Joint details in Modell lead to difficulties in two tests, and this aspect of the design is discussed in detail.

This book was released on 2020 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: In structural reliability analysis, load and resistance factors are calibrated using various methodologies. Proper calibration of load and resistance factor is essential to obtain the design confidence to meet the design consistency or to obtain a desirable reliability index. The reliability index thus calculated is the measure of the reliability of the structural design. Closed-form solution is an elemental method to determine the reliability index for simpler loads and resistance cases. In some basic cases such as when both loads and resistance are normally or log normally distributed, exact solutions are obtained. But in almost all cases, loads have normal distribution, and resistance has log-normal distribution. In such cases, more rigorous and advance calibration techniques are used to calculate the safety index such as Rackwitz - Fiessler procedure and Monte Carlo Method. In this study, the computer-based Monte Carlo Method was used to calculate the safety index or reliability index. The objective of this study is to describe such methodologies to determine the reliability of the structural designs. In this study, reliability analyses are performed to calibrate load and resistance factors using AASTHO LRFD bridge design specifications for reinforced concrete T-beam bridge girders. Reliability indices are calculated for the three spans continuous bridges with equal span length. Both exterior and interior girders are studied to understand the effect of loads and their trends. Reliability analysis suggests that bending moment is governing over shear. Similarly, there is a significant increase in contributions of dead loads over live load for bending and shear with the increase in span length. Systematic variations of the load and resistance parameters are done to investigate the change in reliability index. Various graphs for reliability index versus sets of statistical and design parameters are plotted for the parametric study. Separate graphs are plotted to understand the trend of the change in the reliability index with such parameters. The study showed that there is an increase in reliability index with gradual increase in magnitude of load modifier, live load scalar, and resistance bias for both bending and shear effects. However, there is no significant changes in the reliability index for the increase in dead load scalar and the reliability index decreases with an increase in live load bias. This study will facilitate the users of load and resistance factor design specifications such as AASTHO LRFD for understanding the calibration process of load and resistance factor. This will assist the designer to incorporate the local experience and data while designing the reliable structures.
