THE COMPONENTS OF STEEL STRUCTURE

There are several components of steel structure which can be divided in two general types ; Main Frame & Connectors.

Main Frame ==> Beams, columns, girders, hollow section structural, bar, etc.

Wide Flange Beam(also known as W-Shape)

Connectors ==> Structural tee, angle, channel, plates, etc.


Structural Tee

Usually used as a connectors..but also can be used as tee beam or floor.


Channel (C-Shape)

Angle (L-Shape)

TOPIC 1 : STEEL STRUCTURE

INTRODUCTION

Steel, strong and stiffs, is a material of slender towers and soaring spans. Precise and predictable, light in proportion to its strength, it is also well suited to rapid construction, highly repetitive building frames, and architectural details that satisfy the eye with a clean, precise elegance. Among the metals, it is uniquely plentiful and inexpensive. If its weakness - a tendency to corrode in certain environments and a loss of strength during severe building fires - are held in check by intelligent construction measures, it offers the designer possibilities that exist with no other material.

SYNOPSIS

CONSTRUCTION TECHNOLOGY 3 course exposes students to the technology
involved in the construction. The course emphasizes is on the steel structure, long
span roof, external works, basement and advance building structure. This course also
gives students knowledge on renovation works.


1.0 STEEL STRUCTURE (04 :00)
This topic elaborates on the component of steel structure,
types of joint, Uniform Building By-laws clauses related to
protection of corrosion and fire, selection factors related to
cost, time and quality.

2.0 LONG SPAN ROOF (06 : 00)
This topic explains the construction of lattice roof, portal
frame roof, shell roof and finishes, natural lighting and
ventilation of long span roof.

3.0 BASEMENT (04 : 00)
This topic covers the construction of basement, methods of
excavation and relevant clauses in Uniform Building By-
Laws.

4.0 EXTERNAL WORKS (06 :00)

This topic covers the construction of external works that are
site clearance and earthwork, drainage, landscape,
roadwork, road furniture, retaining wall, fencing and gate.

5.0 INDUSTRIALISED BUILDING SYSTEM AND GREEN
TECHNOLOGY (04 :00)
This topic covers the Industrialized Building System (IBS)
and green technology to develop sustainable buildings in
the construction industry.

6.0 RENOVATION WORKS (06 : 00)
This topic explains the renovation works, underpinning
works and safety factors in execution of the works.
