This article deals with the problem of improving the seismic strength of mechanical structures using a tendon system as actuation device. It consists of a pair of tension cables transmitting a control torque to the structure at the moment arm position. The purpose of the article is to establish the analytical framework consisting of mathematical modeling of cantilever beam under active tendon structural control, analyze the stability, and determine the physical characteristics of tendon system leading to the suppression of horseshoes chaos. The control efficiency is found by analyzing the behavior of the controlled system through the Melnikov methods. We also provide the critical control gain parameters leading to the efficiency of the control process.
