In 2007, ACMA (American Composites Manufacturers Association) and ASCE (American Society of Civil Engineers) jointly developed an LRFD (Load Resistance Factor Design) standard for pultruded composites. LRFD refers to a design methodology that makes use of load and resistance factors based on the known variability of applied loads and material parameters. The development of the LRFD standard is expected to significantly influence the universal acceptance of pultruded composites (Busel, 2008).

Traditional definitions of safety factors in terms of strength requirements, such as load-resistance factors or allowable stresses, are not applicable in blast resistant design. Safety factors arc more appropriately measured in terms of strain energy demand versus strain energy absorption capacity, Allowable deformations arc a practical method to quantify energy absorption capacity. 

For structural and cold formed steel, the Load and Resistance Factor Design (LRFD) method is used. The Strength Design Method is used for reinforced concrete and masonry materials. Details on the Implementation of these methods arc given in subsequent sections in this chapter for each class of material. 

It was mentioned earlier that the level 1 methods include the limit state approach of Section 4.4. There are, however, alternative formulations of the problem and eight recent papers outline North American work in so-called Load and Resistance Factor Design (LRFD) [71]. If the strength effect function can be characterised by R = R FP then the mean and coefficient of...

Many current design manuals for transportation projects use the load and resistant factor design (LRFD) method (AASHTO 1998 and 2012). This procedure is based on the latest multiple ultimate states theory combining with statistic data treatment results as much as possible. This method uses different load factors for the different limit states and strength reduction factors. All stability checks and section strength checks are based on the same procedure, but there are different load and resistant factors for each specific case.

For design purposes, interaction equations are generally used to consider the combined effect of axial load and bending moment. The interaction equations suggested by the American Institute of Steel Construction s Load and Resistance Factor Design manual (AISC 2005) for two-dimensional structures are used for this illustrative example. They can be expressed as ...
