Image of page 2
Instructional Objectives: At the end of this lesson, the student should be able to: state the two types of problems that can be solved using the design charts of SP-16, mention the three sets of design charts specifying their parameters, state the approximations, limitations and usefulness of the design charts of SP-16, mention the different steps of solving the analysis type of problems using the design charts of SP-16, mention the different steps of solving the design type of problems using the design charts of SP-16, apply the methods in solving both types of problems using the design charts of SP-16. 10.25.1 Introduction Lesson 24 explains the procedure of preparing the design charts of short rectangular reinforced concrete columns under axial load with uniaxial bending. It is also mentioned that similar design charts can be prepared for circular and other types of cross-sections of columns by dividing the cross-section into several strips. This lesson explains the design of rectangular and circular short columns with the help of design charts. It is known that the design of columns by direct computations involves several trials and hence, time taking. On the other hand, design charts are very useful in getting several alternative solutions quickly. Further, design charts are also used for the analysis of columns for safety etc. However, there are limitations of using the design charts, which are mentioned in this lesson. Several numerical problems are solved in this lesson for the purpose of illustration covering both analysis and design types of problems using the design charts of SP-16. Version 2 CE IIT, Kharagpur
