    Course Summary

    Course Code: CE 315
    Course Title:   Design of Concrete Structures I

    In this course we will primarily deal with the  design of different concrete structures. Good Luck!! 

    ***OBE based Course Summary***


    Objectives

    This course integrates material from previous structural analysis and design courses and extends the knowledge and abilities of the students in structural behaviour and design. The general objectives are for students to develop an understanding of behaviour, and to develop abilities in design of reinforced concrete. To achieve these objectives, students apply their knowledge of mathematics, science, and engineering while identifying, formulating, and solving structural design problems; the students design structural components to meet current code criteria. The techniques and skills used by the students  prepare them for engineering practice. 

    At the end of this course, students should be able to:

    • Explain the concept of USD and alternate (WSD) design methods for flexure and mechanics involved during different stages of a loaded beam ie. uncracked, cracked, failure.

    • Analyze and design different (singly reinforced, doubly reinforced and T-beam) reinforced concrete beams for flexure.

    • Understand the shear behavior and conduct shear design of reinforced concrete beams.

    • Sketch all types of reinforcement details of reinforced concrete beams that account for development length, anchorage, and splicing of reinforcing bars.

    • Analyze, design and detail one-way and two-way edge supported slabs.

    Syllabus

    • Fundamental behavior of reinforced concrete
    • Introduction to strength design and alternate design methods
    • Flexural design of beams (singly reinforced, doubly reinforced, T-beams) using strength design method
    • Shear, diagonal tension and torsion of beams
    • Bond and anchorage
    • Design of one-way slab
    • Design of two-way edge supported slabs: using strip and alternate methods

    Prerequisites (Course requirements)

     Basic understanding of concrete and steel are expected.

  • Topic 1: Introduction to RCC


    Introduction

    Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. This topic will introduce reinforced cement concrete (RCC) to the students.


    Lesson Objective

    • Understand the reinforced cement concrete (RCC) 
    • Learn the corresponding material behavior 

    Lesson Plan

    The topic objective will be met through the definition, example and subsequent mathematical example of the topic. The understanding of the student will be accessed by relevant forum discussion, quizzes and other activities.

    Introduction

    One way slab is a slab which is supported by beams on the two opposite sides to carry the load along one direction. The ratio of longer span (l) to shorter span (b) is equal or greater than 2, considered as One way slab because this slab will bend in one direction i.e in the direction along its shorter span. This topic will deal with the design of a typical One way slab.
