SummaryThe presentation is based on concrete and starts with the objectives of the presentation and moves onto a review of the composition of concrete. It then moves towards RCC structures and covers points like methods used in the designing of RCC structures, the codes used and the functions of reinforcement. The topics covered after these are the grades of concrete, the workability of concrete, the water content of concrete and the different tests that concrete must pass. The next topic in the presentation is the different pacing conditions according to IS 456-2000 which is followed by the water and cement ratios and the strengths and grades of concrete. After this is covered Concrete mix and its types followed by various methods used for determining the life and strength, like the Limit State Method(LSM), of concrete. What follows this is an explanation of the technicalities of the strength of this material by looking at the stress strain curve, stress block parameters, calculations of how much load can be taken by the material, etc. The information that follows this is the modes of failures of RC beams followed by the effective span for a cantilever slabs along with an explanation of the different types of reinforcement that can be provided. After this will be the turn of the neutral axis and an analysis of the three cases that arise due to the position of the base after which will be covered the design of the continuous beams. The concluding topic will be that of the design of effective stairs covering points like the types of stairs, components of a staircase, the requirements of good staircase, longitudinal span of the stairs and load calculations.
