This document provides instructions for Assignment 2, which is due on October 13, 2016. It describes a slab-beam system in a building where the beam and part of the slab must act as pre-cast concrete. It lists various structural properties and loads and asks the student to (a) calculate design actions on beam B/1-3, (b) draw shear and bending moment diagrams for the beam, and (c) design and classify the tension reinforcement required using a stress block diagram.

ASSIGNMENT 2

(INDIVIDUAL)

DUE DATE: 13/ 10/2016

Figure Q2 shows the plan view of slab-beam system in one building. Due to construction works,
beam and a part of the slab has to act as a pre-cast concrete slab. Given;

Slab thickness = 125 mm


Beam size = 250 mm x 600 mm
Finishes = 1.0 kN/m 2

Ceiling = 1.0 kN/m 2

Weight of concrete = 25 kN/m 3

3 m height brickwall = 2.6 kN/m (entire building)


2

Characteristic variable action, qk = 3.0 kN/m2


Characteristic. strength of concrete, fck = 25 N/mm2
Characteristic strength of steel, fyk = 500 N/mm2

(a) Calculate design action act on beam B/1-3


(b) Draw shear and bending moment diagram for beam B/1-3
(c) Design the area of tension reinforcement (As) required of the section by using the stress
block diagram and classify either the section is under or over reinforced. Assume the
depth to compression reinforcement and tension reinforcement are 50 mm and 410 mm,
respectively .
