Reliability based design in civil engineering. Introduction to enginering design. It is also uniquely compatible with the theoretical basis underlying other disciplines such as structural design. Reliability based design is the only engineering methodology currently available which can ensure self consistency in both physical and probabilistic terms. Performance evaluation and expectations.
Homework collectively worth 25 of the grade. Reliability based design in civil engineering. The important general design principles explained here are concept of safety factors allowable stress design load and resistance factored design plastic design limit state design and life cycle cost design. Spatial variability using random fields.
Probability theory and conditional probability graphical representation. The lrfd load and resistance factor design format of rbd is used by the aashto specifications and the major developments relevant to pile design in general and dynamic testing in particular will be presented. A term project worth 25 of the grade and due on december 101999. It can be said that a system must be reliably safe.
Reliability engineering relates closely to quality engineering safety engineering and system safety in that they use common methods for their analysis and may require input from each other. The chapters are well planned beginning with probability and statistics. Codes worldwide moved to rbd reliability based design. As an illustration the developed procedure is used for flexural design of interior t beams of a rc bridge with and without considering corrosion effect subjected to various design constraints and service lives.
Perform reliability based design of a civil engineering system of your choice. Reliability based design accounts for uncertainties scientifically whereas deterministic design does not rbd assigns a specific reliability on a design through pf probability of failure it is not bad for a system to have probability of failure but bad not to know how much. Your performance in the course will be evaluated based on the followingcomponents. The procedure simultaneously maximizes the reliability of the structure and minimizes the material costs given a design service life.
