Analysis of partially prestressed concrete rectangular waffle slabs subjected to cyclic knife edge loading (KEL) / Ahmad Arifin Kasah

This project is an attempt to study the behaviour of partially prestressed concrete rectangular wafïle slabs of different sizes and number of waffles. With the aid of a computer program available in CADEM Centre at Institut Teknologi Mara (ITM) , in particuiar ANalysis SYStem ( ANSYS ) Version 5,0 , developed from finite element methods, the analysis can be done with respect to the purpose of this study. Three specimens of partially prestressed rectangular waffle slab are modelled and analysed using the software. The specimens namely WR 01 , WR 02 and WR 03 are similar in the overall size but with different size , and number of waffles and ribs within them. The output will be compared to the results that had been obtained from previous laboratory testing . Results are examined in terms of load - deflection, stress – strain relationships and expected crack propagation.
