Channel-type lining board is a structural steel member for subway and basement facilities of the building constructions. It is well known that lining board contacted with underground is exposed to corrosion environment factors which are high humidity, temperature and gases. This paper evaluates the corroded lining board strength by thickness loss of plates which are component of the board The three points static loading tests were performed and stresses of the plates and middle point deflection were measured The thickness losses of the plates by corrosion make more vertical displacement and stress increasing under the DB design load which is considering vehicle impact factor.
