American Advanced Steel Systems

One Vision, a concept in steel solutions that move a better world...

The system more efficient

and cost competitive for steel structures.

All over the world people are ever more concerned about for quality, details and delivery of the construction.

This is a feature of the level of a country’s development; the more advanced in social and technological terms, the more attention is devoted

to the definition and specification of the products to be applied to a building.

This is the reason for the success of the AMERICAN ADVANCED STEEL SYSTEMS.

Since it’s creation AMERICAN ADVANCED STEEL SYSTEMS has been developed to meet these requirements.

American Advanced Steel Systems is the outcome of a detailed project, a process of industrial fabrication and production-line assembly.

In this catalog we shall deepen the concept of industrial product and the result of this concept, where details developed

prove to be applicable in all the elements of the AMERICAN ADVANCED STEEL SYSTEMS, with no improvisation,

assuring always the same standard of quality.

Having quality does not mean costing more. A specified project for our system

allow us to take full advantages of an integrated system, resulting in lower

costs and shorter performance times.

These are the factors that guide a project without affecting quality.

AMERICAN ADVANCED STEEL SYSTEMS is an exclusive Structural

System of Metallic Roofing created and developed by TANGENT STEEL

INDUSTRIES in use since 2004 for various types of buildings and spans.

Thousands of square meters have been installed on the five continents.

As a result of it’s features, AMERICAN ADVANCED STEEL SYSTEMS

marks the start of a new culture, with all the possibilities this represents.

The AMERICAN ADVANCED STEEL SYSTEMS continues to be the

leading edge in the development in Metallic Structural Systems.

A Short History

Introduction

TS

Unique ConceptAMERICAN ADVANCED STEEL SYSTEMS is an integrated system of structure and metallic roofing.

It consists of trusses laid out in parallel in modular form, on top of which, in a two by two formation, continuous coils of coated steel

(Galvanized, Alu-Zinc or Pre-Painted) are unwound, with no joints, holes or overlaps, creating channels running the whole length of the roof.

It’s a watertight system, highly-safe, allowing slopes of up to 1%.

AMERICAN ADVANCED STEEL SYSTEMS has introduced exclusive features in the concept of metallic roofing.

The concept of Roofing System is expressed in the integration of the structure and the roof, regarding the roofing as a whole, rather than

a separate parts, as used to be the case.

The American Advanced Steel Systems

TS

Coils of coated steel (Galvanized, Alu-zinc or Pre-painted),

which are unwound on the structural modules,

forming continuous channels for carrying water,

with minimum lowering.

Beams or trusses of coated steel (Galvanized, Alu-zinc or

Pre-painted) laid out side-by-side and bridged to one another

by transversal parts, forming a practically level plane.

TS

Manufactured on state of art automated machineries, the parts of

the AMERICAN ADVANCED STEEL SYSTEMS are produced under

the strictest quality control.

The exclusive industrial process of AMERICAN ADVANCED STEEL

SYSTEMS, allows regulating inventory to be kept, assuring prompt

delivery, thus cutting down the “lead time” necessary in traditional

processes.

As for transportation, TANGENT STEEL can guarantee

that AMERICAN ADVANCED STEEL SYSTEMS can be

transported by ship, truck, trailer or container, with a

full load with relative ease and reduced cost.

�The reduction in delivery times, controlled warranted quality,

and production-line assembly are fundamental parameters for

quality with economic benefits.

The Design of the AMERICAN ADVANCED STEEL SYSTEMS is comprised of standardized and interchangeable parts, fitting together perfectly,

easy to ship and store, manufactured with all the holes / fixing points necessary for the installation of any complementary material.

Length of the Building

- Length of the Modules - in principle there is no limitation

on the overall length of the modules, however, to make

better use of them, or a better aesthetic result,

it’s recommend that this size is always a multiple number.

In the determining “B”

In determining “A”- Length of the Building -, 20cm must added;

this referring to the width of 1 module, as indicated:

TS

Mass production, serial fabrication and the concept of

interchangeable parts allow complements and installations such as zenith

lighting, thermoacoustic insulation, industrial fans, running ducts through the

roofing, among others, these being used in all the models and applied in the

same manner, with no improvisations.

No improvisation means that in the AMERICAN ADVANCED STEEL SYSTEMS these solutions are not provided for one project

or one construction, rather, they are foreseen in the system. When there is a requirement for additional scopes of work, all the

details for its perfect execution are there, as all the components of the system come prepared to handle these situations,

irrespective of their existence or not.

Varying only the height or the distance of the modules, we obtain the AMERICAN ADVANCED STEEL SYSTEMS family.

There are various models, capable of overcoming different spans and loads, according to the needs of a project, so that the constructive

details that complement the product are always compatible.

With AMERICAN ADVANCED STEEL SYSTEMS,

TANGENT STEEL introduced the concept of the Automotive and

Aeronautics Industry into Civil construction.

Within this concept, different modules use the same platform,

serving all requirements.

Our technical department used the traditional model as the basis for

a family of new products focused on the demand of the market,

while maintaining the basic features of the system unchanged.

Standards and Models

TS

The components of the AMERICAN ADVANCED STEEL SYSTEMS

are supplied in Galvanized Steel and Alu-zinc with a flow tension of

250 Mpa.

For connecting the parts, galvanized bolts and locking nuts are used.

The AMERICAN ADVANCED STEEL SYSTEMS, from the structural standpoint, consists of a plurality of beams laid out parallel

and locked sideways, thus making up a highly-resistant assembly.

For dimensioning the structural modules, the method of limiting states was used, according to the procedures and concepts recommended by the

standard .AISI-LRFD - American Iron and Steel Institute Load and Resistance Factor Design Cold-Formed Steel Structural Members Manual 2001 -

Generally speaking, cantilevers with a length of up to 30% of the span can be admitted.

Stability of the System

TS

1 - As the AMERICAN ADVANCED STEEL SYSTEMS

forms a practically leveled plane, with minimum

slope of up to 1%, the wind loads acting on the

roofing are generally suction.

As per standard of AISC-1996-LRDF, in calculating2 -

the elements submitted to wind loads ( pressure

and suction ), the weighting coefficient may be

reduced by 10% (x 0.9).

The combinations of actions used for calculating the resistance of the structural modules are those stated by AISC-1996, as per table below.

Loads

Combinations of Actions

1.2 PL + 1.6 AO PL = Permanent Load; AO = Accidental Overload

PL = Permanent Load; WL = Wind loads (Pressure and Suction)0.9 PL + 1.3 WL

Example of the use of the Table

For an initial calculation of the combinations actions, an average weight

of 20kgf/m² of permanent load will be considered, due to the roof’s own

weight. We shall thus have the following hypotheses of calculation:

1) 1.2 PL + 1.6 AO = 1.2 x (20+5) + 1.6 x (25+10) = 86.0kgf/m²

2) 0.9 PL + 1.3 WL = 0.9 x (20) + 1.3 x 0.9 x (-80) = 75.6kgf/m²

As the structural modules of the AMERICAN ADVANCED STEEL

SYSTEMS have a horizontal axis of symmetry, that is, they resist vertical

loads in the same way regardless of direction (upward or downward),

the effort most unfavorable to the load must be adopted, irrespective

of whether it is suction or pressure. Thus, the critical load effort is that

of load combination 1 that is 86.0kgf/m².

In the case of a vector calculation, the loads must be considered

according to their direction. We arbitrate positives downwards.

Suppose it is necessary to design an AMERICAN ADVANCED STEEL

SYSTEMS ROOFING for a permanent load of 5kgf/m², a working

overload of 25kgf/m², plus 10kgf/m² of accidental overload.

After analyzing the influence of the wind on the roofing, we reach a

maximum suction load to be applied to its surface, equal to 80kgf/m².

This analysis must consider the characteristic speed of the wind in the

region of the work, plus the influence of the internal and / or external

pressure coefficients (using, example, standard forces due to the

wind in building).

The AMERICAN ADVANCED STEEL SYSTEMS does not allow water pressure on the areas of penetration

in the roofing. The pressure of the water is eliminated, running it off to the side coils.

The safety in this system lays in the design, and does not depend on the skill of the assembly crew.

By diverting the flow of water to the free side coils, and respecting

the separation of the modules of the system, the necessary space is

opened for running ducts of any dimension.Tops of Interfering FactorsPenetrations in the Roofing

Remarks

1) The quantity of heat reflected by the

galvanized steel roof during the trials

remained at around 98% of the heat

irradiated.

2) To conduct the trials, the lower part

of the bench was duly insulate with

cardboard, seeking to avoid the

circulation of air inside it.

Through trials and studies carried out by the “São Paulo State University - UNESP - Brazil” we have verified the performance

of AMERICAN ADVANCED STEEL SYSTEMS against similar roofing materials, (see table below).

Results

Considering the energy absorbed by AMERICAN ADVANCED

STEEL SYSTEMS without insulation, the factors of form and

thickness demonstrate that the product has better insulation,

with less retention of heat, when compared with a roof of

galvanized steel.

Supports:In projects where it is necessary to fix a siding (metallic Sheeting,

concrete panel, among others) a diagonal is added to the lower

level of the structural module of the AMERICAN ADVANCED

STEEL SYSTEMS creating a horizontal truss.

This is convenient for transferring the horizontal efforts of the

wind to the supports of the roofing, see figure 10.2.1.

The AMERICAN ADVANCED STEEL SYSTEMS can be fixed directly to

metallic support.

See fig. 10.1.1

On concrete supports, it is necessary to use a part that we denominate

“Metallic Cradle” to adapt one structure to the other.

See fig. 10.1.2

For structures on concrete panels (Pre-casted without columns),

a metallic support is the solution to join one structure to the other.
