This study examines how bending deflections impact the static and dynamic performance of masonry columns, highlighting the importance of second-order effects on collapse load and dynamic properties through numerical analysis.

Contribution

It introduces explicit solutions and investigates the combined effects of nonlinearities on masonry columns using an iterative numerical method.

Findings

Second-order effects significantly influence collapse load.

Deflections alter the dynamic properties of masonry columns.

Explicit solutions aid in understanding nonlinear behavior.

Abstract

This paper studies the influence of bending deflections on the structural behaviour of masonry columns. Some explicit solutions are presented, and the combined effects of the constitutive and geometric nonlinearities are investigated through an iterative numerical procedure. The results show that considering second-order effects affects both the collapse load and the dynamical properties of masonry beams significantly.
