PROGRESSIVE STRUCTURAL FAILURE ANALYSIS OF PLANE TRUSSES

ABSTRACTA lot of assumptions,simplifications and approximations are made in the deterministic design of structures in the process of substituting a real physical system, whose behaviour is inherently random, with a mathematical model. Resort is therefore often made to the application of safety fa...

Unsymmetrically Reinforced Concrete Columns Under Small Eccentricity of Loading

ABSTRACTReinforced concrete columns under Small Eccentricity of loading have not been given adequate attention as a class of columns which require its own design method. The present assumption is that current theories on columns which regard eccentricity as a purely flexural parameter, are adequa...

COMPARISON OF FLOOD FREQUENCY ANALYSIS METHODS FOR RIVER TARABA

ABSTRACTWater resource designs based on flood are perfect examples of decisions under uncertainty. Three types of uncertainties may exist in a flood design problem - when the classical method is used. These are natural, parameter and model uncertainties. To reduce the parameter and model uncertai...
