Stability Check Of RCC Chimney Using Health Monitoring.

Abstract

Chimney is a tall slender structure and the primary function of the chimney is to discharge pollutants into the
atmosphere at such heights with sufficient velocity such that the gases and suspended solids (ash) are dilute due to
atmospheric turbulence and concentration of pollutants are deemed harmful to the environment over a defined spread
such that their concentration, on reaching the ground is within regulatory limits. Chimney have different associated
structural problems and must therefore be treated separately from other forms of tower structures. Damage to the
chimneys leads to shut down of the industry and power plants. So, structural health monitoring of RCC chimney is
required for find out the stability, service life and condition of RCC chimney. This paper proposes a wireless micro
electro mechanical system (MEMS) inclinometer sensor for structural health monitoring (SHM) that can be applied to
RCC chimney subjected to various loadings. Inclinometer sensor used in this study for finding out the deflection of
chimney and check the deflection data given by the sensor with the deflection value calculate by the classical approach
using codal provision standards and STAAD Pro. This type of in-situ, non-destructive structural health monitoring is
implemented for stability check of RCC chimney.
