Abstract

A multi-scale monitoring method for local seismic damage of RC structures has been proposed.Firstly

on the material scale

smart aggregate monitoring was conducted to consider the effect of randomness of concrete material in meso-scale

and tests were carried out to establish the statistical relationship between the stresses of smart aggregates and the stress in concrete during the overall damage process.Secondly

on the cross-section scale

by using MEMS inclinometer to measure the rotation in structural cross-section

a monitoring method is proposed to obtain sectional curvature of concrete members and its feasibility is evaluated through experiments.Finally

on the member scale

a monitoring method is developed to obtain the inter-story drift

which is based on the integration of monitored crosssection rotation by using MEMS inclinometers.The design principle of the monitoring locations is given and its reliability is validated through specimen loading test.
