Seismic analysis of inelastic cantilever column systems

Abstract

Seismic analysis still has many issues to be investigated not only in countries which are situated in seismic regions but also in European countries, as it was seen in Italy, Greece and Turkey in 2017 [1]. Based on calculations, methods of theoretical and experimental research we performed synthesis reactions of the structural systems of the console type on the seismic effects. To identify structural architectonics of objects, a regular structure which includes geometrically non‐changeable (or slightly changeable) vertical spinal fragments and seismic safety bearing members with plastic hinges at the nodal connections is used. The determining factor of the stress‐strain state of the structural system is the angular displacement relative to the base in the form of deviations close to the rectilinear approximation. The method of seismic analysis of inelastic cantilever column systems of regular structure is developed [2]. The method is based on the energy principle for analysis of inelastic systems as a quasistatic problem. The results can be extended for ecological materials such as bamboo [3].

A study of dynamic characteristics of variable cross-section cantilever hollow cylinder under impact load

“…L A Borodin et al [8] conducted the seismic analysis on the inelastic cantilever column system and reduced the vibration analysis of the inelastic system to a quasi-static problem. S M Darbandi et al [9] studied the static stability of variable cross-section columns under distributed axial force, and obtained the closed solution for calculating buckling load and corresponding modal shape.…”
