Abstract

The usual linear shape function for approximating axial displacements in beam finite elements used as eccentric stiffeners or as portions of composite cross‐sections, leads to an error in the static deflection. A modified element reduces this error. The behaviour of these two elements under free vibration is examined. The linear element is shown to be in considerable error in the dynamic case also.

A simple form of measurement error model for explanatory variables is studied incorporating classical and Berkson cases as particular forms, and allowing for either additive or multiplicative errors. The work is motivated by epidemiological problems, and therefore consideration is given not only to

In the Newmark and other approximate step-by-step methods, having introduced assumptions in order to transform the differential equations, which are characteristic of response problems, into simultaneous equations, successive solutions lead to a response-time history. In this paper numerical results
