Arash Lashkari
Structural Designer, EIT
Modern life is almost wholly dependent on engineering. Engineering means creation. It is everywhere and it is always
changing, and it is this in particular which attracts me to structural engineering. In this field I can combine my
knowledge and skills in physics and maths, two subjects which particularly interest me, and also work in an area
which is both diverse and exciting.
I am professional, capable, and motivated with over 8 years' experience in design of various types of structures
including mid-rise and high-rise residential, commercial, hospital, small bridge, school and industrial structures.

PROJECT LOCATION
Project is located in the city of Toronto, Ontario,
Canada.
City of Toronto has different region and this
Structure is located in North York
Toronto
This is a one story industrial steel
structure
The structure area in total is 1450
square feet with 5.5 m height.
Building
Design Approach
Structure was designed by
SAP200 software based on
Canadian standards including
Canadian National Building Code
(NBC), Ontario Building Code (OBC)
and American Code (AISC)
Industrial Structure
Project Introduction
DESIGN LOADS
Gravity Loads are
included dead and live
loads
Gravity Loads
Lateral Loads is
included wind load
Lateral Loads
Snow, ice or rain
loads
Snow Load
The design load is the maximum amount of something a structure is designed to handle or the maximum amount of
something that the system can produce
Standards
• Specification for Structural steel buildings, AISC360-10
• National Building Code of Canada, NBCC 2010
• Ontario Building Code, OBC 2012
Software
• CSI SAP2000 (for beams and columns)
• CSI SAFE (for foundation)
GRAVITY LOADS
Dead Load: 0.5 kPa
Live Load: 1 kPa
• The dead load includes loads that are relatively
constant over time, including the weight of the
structure itself, and immovable fixtures. Dead loads
are permanent or static loads.
• Live Loads were extracted from Ontario building Code
(OBC) and National Building Code (NBCC 2010)
