The document discusses the design and construction of a new art museum building in Denver, Colorado. Some key points: - The building's design by architect Daniel Libeskind emulates the jagged peaks of the surrounding Rocky Mountains with its sharp angles and complex geometry. - It is constructed out of steel, concrete, and other materials like titanium and granite to withstand the lateral forces without right angles or vertical walls. - The engineering was extremely challenging due to the unconventional sloped designs of the walls, floors, and other structures without standard angles. Precise fabrication and installation was required. - Over 100 steel columns extend from the foundation into the bedrock to support the entire weight of the building in

2. Regarding the entire design concept, Libeskind commented, “The project is
not designed as a standalone building but as part of a composition of public
spaces, monuments and gateways in this developing part of the city,
contributing to the synergy amongst neighbors large and intimate.” Libeskind
designed a landscaped pedestrian plaza for the DAM complex, which also
displays significant works of outdoor sculpture.

3. The new building is located directly south of the twin towers of the original
building, and adjacent to the Denver Public Library, designed by Michael
Graves.
Is the core of the new cultural district of the city. The entrance is opposite the
new plaza that links the Civic Center in Golden Triangle, a neighborhood of
villas, before scorned, which is currently being converted into a fashionable
neighborhood.
From the inside, visitors can see the mountains and the city of Denver.

4. The sharp angles and the complex geometry of the Denver art museum’s Frederic C.
Hamelton building emulate the jagged peaks of the surrounding Rocky Mountains .
The project is designed as a single building, but as part of a composition of public
spaces, monuments and gateways in the development of this part of the city, which
contributes to the relationship with neighboring buildings.
The most striking feature of the museum is the triangular shape of a corner that is fired
out of the street toward the old Gio Ponti building.

5. Other forms are deployed out into the square, partially covering the entrance.
But the generality of the exterior lies in how it changes its appearance when
looking in different directions. Fragments of a peak can guess outstanding
between the towers of the city. From another angle, the structure seems static
and has the appearance of búnquer. At night, the building tends to give a visually
achatarse strange sense of stillness.

7. A driven pile is a relatively long, slender
column, provided to offer support or to resist
forces, made of preformed material having a
predetermined shape and size that can be
physically inspected prior to and during
installation, which is installed by impact
hammering, vibrating or pushing into the earth.
Driven piles are usually the most cost
effective deep foundation solution.
You pay only for what you need.
There are no hidden extra costs or
added expenses for site clean-up. The
wide variety of materials and shapes
available for driven piles can be easily
fabricated or specified for high
structural strength, allowing them to
be driven by modern hammers to
increased working loads thus
requiring fewer piles per project,
resulting in substantial savings in
foundation costs.

8. Circular and H shape Steel foundation piles used in the
structure .
The depth of the foundation reached to 7 m below the
ground .
Chosen to work efficiently with the rocky mountains soil
and to achieve the higher stability pleased .

9. The 2,740 ton of steel superstructure is an
interwoven cluster of leaning braced
frames and trusses . More than 3100 pieces
of steel are contained by 20 sloping planes
that define the structure . None of the
planes are parallel or perpendicular to one
another ,Almost all the steel used was
fabricated in the US.
The 5658 cubic meters of reinforcement
concrete with graded aggregates.
The slaps were cut in four different sizes
: 6” , 9” , 18 with 12” as the common
dimensions. The mix was Situ Casted due
the special needs ,specifications and
different dimensions and angles .

10. Nine thousand panels of titanium
cladding and over five thousand blots
were used in the museum, That will
connect Denver to the new millennium.
A smooth black pearl granite was
chosen , in order to install the staircases
and floors of one of the most innovative
museum ever built.

12.  The unconventional and modern interior design resulted in sloped
walls with no right angles to carry the weight of the building ,meaning
no plumb staircase or floor lines either ,which greatly challenged
every trade involved in the process.
 There isn't aright angle in the building , and every stone slab had to
be angle cut into the wall .it was ultimate challenge.
 Denver is not an area prone to earthquakes, but because of the
building’s challenging geometry, the structure was designed to
withstand lateral forces beyond what would be required for regions
with the greatest seismic activity and concretes inherent nature to
shrink and cracks as it cures.

13.  Except for its central elevator core, the building has no true vertical
walls. Its ceilings and risers slope at all angles. The engineering
challenge was to create a stable supporting structure for a building
that did away with typical means of support.
 With walls leaning outward, the form required Arup to design the
floor framing system to manage heavier lateral loads. Like a ship .

14. The 3 largest steel beams weigh 550lb per linear foot
and are 60ft long - so long that the only company able
to fabricate the steel is based in Belgium.
Mortensen used a 3D state-of-the-art computer
programmed to map the location of every steel rod
before it was installed.
The company also applied a fireproofing material to all
of the steel.
116 vertical columns of steel and concrete extend from
the building's foundation in to the bedrock.

17. H Beam made of structural steel is a beam with
an H-shaped cross-section, which is widely used in
construction and civil engineering. H Beam is a
very efficient form for carrying both bending and
shear loads in the plane of the web. On the other
hand, the cross-section has a reduced capacity in
the transverse direction, and is also inefficient in
carrying torsion, for which hollow structural
sections are often preferred , and its also known
as I beam.
APPLICATION:
Commercial building structure
Pre-engineered buildings
Machinery support structures
Prefabricated structure
Medium scale bridges
Sizes:100mm to 900mm

18. APPLICATION:
Warehouses Car parks
Workshops Grandstands &
Sport stadiums Multi-story
frame structures
Sizes:50mm to 300mm .
The structural channel, also known as a C-beam,
is a type of (usually steel structure) beams, used
primarily in building construction and civil
engineering. Its cross section consists of a wide
"web", usually but not always oriented vertically,
and two "flanges" at the top and bottom of the
web, only sticking out on one side of the web. It is
distinguished from I beams or H-beam or W-
beam type steel cross sections in that those have
flanges on both sides of the web.

19. APPLICATION
 Trusses
 Transmission towers
 Telecommunication towers
 Bracing for general structures
 Stiffeners in structural use

20. Size： 10-18mm
square bar

22. Diametre: 8-300mm

23. Wire is 5.5-30mm diameter hot-rolled round
steel, or rather the cross section of the
special-shaped steel. Due to the delivery of
the goods in the form of wire rod, so it is also
known as wire rod.
Application
Wire rod is mainly used as the reinforcement
of reinforced concrete and welding structure
or reprocessed raw material (such as
drawing, nail, etc.).

24. Diameter 8MM-50MM

25. h
Bolted joints are one of the most common elements
in Construction and machine design. They consist of Fasteners that
capture and join other parts, and are secured with the mating of Screw
Threads.

26. Steel to be welded must be of a certain type that permits welding.
A high carbon content, such as that which is found in historic cast
iron, cannot be welded.
Welding is used to attach these tubular members. A simple fillet
weld is used to attach the smaller HSS to the larger one. The
change in size provides space for the weld.

27. Generally in steel work construction, bolted site splices are preferred
to welded splices for economy and speed of erection.
Hollow sections are typically connected by welding while open sections are
connected by bolting or welding, which will usually involve the use of gusset
plates
Small trusses which can be transported whole from the fabrication factory to
the site, can be entirely welded. In the case of large roof trusses which cannot
be transported whole, welded sub-assemblies are delivered to site and are
either bolted or welded together on site.
In light roof trusses entirely bolted connections are less favored than welded
connections due to the requirement for gusset plates and their
increased fabrication costs.

31. Pratt Truss . K Truss .
A Pratt Truss has been used over the past two
centuries as an effective truss method. The
vertical members are in compression, whilst the
diagonal members are in tension.
Advantages
 Aware of member's behavior - diagonal
members are in tension, vertical members in
compression m
 The above can be used to design a cost
effective structure.
 Simple design.
 Well accepted and used design.
Disadvantages ( Challenges ) :
 Not as advantageous if the load is not vertical
The K Truss is a slightly more complicated
version of the Pratt Truss. It's main difference is
that the vertical members have become
shortened - improving it's resistance against
buckling.
Advantages
 Reduced compression in vertical members.
 Possible reduction in steel and cost if
designed efficiently.
Disadvantages (Challenges ):
 Slightly more complex.
 Increased constructability due to additional
members.
