Experimental study concerning reinforced concrete beams under thermal and mechanical loads

In order to verify the results of theoretical research, an experimental study was performed on 13 reinforced concrete beams. A bending restraint force (resultant) or combined restraint and load forces (resultant) were applied to nine beams and also a restraint normal force, in addition to bending, to four beams. The restraint forces were produced by heating the upper or lower sides of the beams. The test beams were reinforced and designed in different ways. Loading arrangements varied with different beams. The most important measurements in a service state were connected with cracking and in the ultimate state with the determination of rotation capacity.
