Residual Strength Analysis Methodology:Laboratory

The NASA Aircraft Structural Integrity (NASIP) and Airframe Airworthiness Assurance/Aging Aircraft (AAA/AA) Programs have developed a residual strength prediction methodology for aircraft fuselage structures. This methodology has been experimentally verified for structures ranging from laboratory coupons up to full-scale structural components. Residual Strength of a Steel-Concrete Composite Summary This paper presents a numerical investigation of the residual strength of a typical PR moment-resistant multi-storey steel framed structure, subjected to a design seismic event followed by fire. In order to allow a calibration with some real results from fire tests on a natural scale, the architectural and structural definitions of the eight-storey steel Cardington building were chosen

Residual strength analysis of AA 2198 laser beam

To meet the future demands of the aerospace industry with respect to safety, productivity, weight and cost, new materials and joining concepts have been developed. Recent developments in the metallurgical field now make it possible to use laser-weldable Aluminum Alloys (AA) of the 2xxx series, such as the AA2198, with a high structural efficiency index due to their high strength and low density.

The degraded members are commonly assessed as not having enough residual strength and thus replaced [5]. However, it may happen that there is no need to remove and replace affected structural elements since the structural safety is still guaranteed or can be achieved with selective strengthening. pdf residual strength of structural Welding steelssn400 (PDF) Structural Use of Glass Ted Singleton - Academia.edu.
