By: Andrew LeBlanc

ET-494

Fall 2013-Spring 2014

Advising by: Rudolph Rode and Byron Patterson

Objective

To design and construct a building in which has the following attributes:

24’x24’

Able to be multifunctional

Leave potential for future development

Overall vision

Self sufficient = Save $$$

Begin 10 year plan

LRFD (Load & Resistance Factor Design)

• Basic Design Equation:

Ru ≤ φ Rn

Force in member ≤ resistance factor * nominal strength (force at failure)

Ru = Σ γi Qi

Force in member = Σ load factor * load effect under service load

Types of loads

D = Dead load

L = Live load

LR = Roof live load

S = Snow load

R = Rain load

W = Wind Load

E = Earthquake load

LRFD Load Combinations:

Gives the overall compression or tension in members in steel buildings:

1.4D

1.2D + 1.6L + 0.5(Lr or S or R)

1.2D + 1.6 (Lr or S or R) + (0.5L or 0.8W)

1.2D + 1.6W + 0.5L + 0.5 (Lr or S or R)

1.2D + 1.0E + 0.5L +0.2S

0.9D + (1.6W or 1.0E)

Codes, Specifications and Standards

Building Codes Legal documents which protect public safety.

• Minimum design loads

• Detailed design, construction and inspection rules for structures in general

• Fire protection requirements for structural members

Most used single national building code: the International Building Code (IBC)

Specifications

Specifications are design guidelines and recommendations published by recognized engineering societies.

– Examples

• AISC (American Institute of Steel Construction)

• ACI (American Concrete Institute)

ADA ( Americans with Disabilities Act)

– Specifications, when referenced by building codes, are legal documents

Estimate

Gives approximation of total project

Detailed description of what particular job will cost

Usually a materials list is included with or in an estimate
