Test loads on the trough slabs of the engine room roof of a power station

Many industrial buildings have had roofs using reinforced concrete trough slabs being in service for over 50 years. There is generally a lack of design documentation and reliable catalogue data cards for them. If the slabs are to be used for a longer period of time, then it is necessary to assess their technical condition and their suitability to safe carrying of the expected operating loads. Instead of making the rather laborious and difficult inventory of the concrete class and type of reinforcement as well as performing of computational analysis of the load capacity of the slabs, the trial test loads on these slabs can be performed. The paper presents the course of such load tests and their results, which allowed to prolong the exploitation of the roof over the engine room building in one of the power stations.
