This paper proposes a damage assessment methodology for the non-structural elements, especially ceiling elements of a building, utilizing an inspection robot. The developed inspection robot equipped with a wireless camera and data processing function has a capability of providing valuable information for the repair and maintenance decision making of a damaged structure. The inspection robots will be able to estimate the damage condition without any process of engineers on-site-inspection involved. The robots also can gather the static data of the nonstructural elements from the sensor, which are distributed on the nonstructural elements. To demonstrate the effectiveness of the inspection robot, the robot is utilized to estimate the ceiling of a real structure damaged by the 2011 off the Pacific coast of Tohoku Earthquake. And conceptual experiment is also conducted for the purpose of evaluating the proposed damage assessment methodology in cooperation with the smart sensor and the inspection robot. The proposed methodology will provide useful information to the maintenance and repair planning of a damaged structure.

Base-isolation system is designed to lengthen the period of the building. However, this can also increase wind-induced responses of the structure since wind forces have long duration and predominant energy on long periods. Furthermore, the mean component in the along-wind direction also causes certain base-isolation components, such as sliding bearings to become prone to creep phenomenon. Despite of this, evaluation methods of wind-induced response considering creep property on highrise base-isolated buildings with sliding bearings has not yet been fully investigated. Therefore, this paper examines the evaluation method on those buildings and clarifies the effect of creep property using timehistory analysis.
