The analysis and design of plate elements is too complex, for most cases therernis no closed form of solution for these are highly intermediate structures whichrnare full of assumptions, and uncertainty makes difficult for day to dayrnapplication and become uneconomical during design. To tackle this,rnresearchers and engineers developed simplified method with acceptablernreliability and accuracy. Still the limitation is visible that some methods arernonly applicable to some particular problems. Hence to control this, codes werernprepared and used in practical analysis and design practices and used tornharmonize the application throughout the country. But many professionalsrnclaim that the practice is not to the standard and may damage the economy ofrnthe country as whole if some devastating earth quake happens. Moreover,rnthese believes care shall be taken in design, construction and service of thernbuildings for the country is under development, projects are becoming costrnintensive and massive in terms of size (in which large number of occupantsrnmay use it).rnIt is clear that buildings shall be safe, economical and serviceable. But is veryrndifficult to attain these requirements the same time , that is, these may needrnmore time, finance and experience with knowledge. Almost all designers claimrnthat the cost provided by most clients extremely unaffordable and time thatrnthey required for analysis and design is too short which leads for inexperiencedrnand unqualified designers to join the practice on the contrast the wellrnexperienced go to large projects. For instance, in this research, it is identifiedrnmechanical engineers participate in design of buildings knowing the analysisrnsoftware alone.rnHence, this study focuses on the actual practice of slab analysis and designrnassessment and evaluation. It covers international and local challenges facedrnduring analysis and design, approval and construction (partly) of slabs. Itrncompares and clarifies our code of practice with respect to relatedrninternational code practice and re-evaluates the country local practicalrn(particularly Addis Ababa and Mekelle) practice with our code of standard.rnMoreover, present and clarifies the methods of slab design and analysis statedrnin our code
