Prestressed concrete structures, such as storage tanks for liquefied gases, may be exposed to severe thermal loading. Inner tank leakage in case of LNG storage implies exposure of the inner face of the concrete wall to a temperature of -165 ºC. In another situation surface temperatures up to 600 ºC can be reached on the dome roof in case of fire. Thermal loading differs from mechanical loadin…
This edition presents the basic theory in prestressed concrete similar to the second edition. The method of load balancing is discussed side by side with the working-load and the ultimate-load methods, forming a tripod for prestressed concrete design
The course deals with design of steel structures using “Limit State Design Method”. The design methodology is based on the latest Indian Standard Code of Practice for general construction (IS 800:2007). The subject covers all the necessary components such as material specifications, connections and elementary design of structural members for designing industrial steel structures. The course…

Beton prategang (prestressed concrete) adalah jenis beton yang diberikan tegangan tekan internal buatan untuk mengimbangi tegangan tarik yang akan timbul akibat beban eksternal, sehingga meningkatkan kekuatan dan daya tahan struktur beton secara keseluruhan.
The practical design of statically indeterminate structures is a trial and error process. Because the elastic equations are dependent on the substance, as well as on the form of the proposed structure, it is necessary to assume the size of each member in advance. This is based primarily on the experience of the designer, but these assumptions must then be justified by computation, and, as a rul…
