This report will investigate the structural makeup of the commercial building we are working on as part of the Studio 2 module. The building has a single-storey basement that is to be used for car parking, with 5 upper storeys comprising of a café and open plan offices. This report investigates firstly the site that the building is situated on, secondly, the structural make-up of the building, thirdly the load trace and finally, materials used along with reasons for choosing them.
The proposed commercial building is to be located on a site at 45 Dominick Street, Shandon, Cork City. The results of site investigations indicate that it has a high water table. The site itself is 0.3 acres with adjoining buildings on 3 out of 4 sides. The main site entrance is through the southern boundary that leads on to Dominick Street, a narrow public road that measures 4.5m across at its narrowest point. The northern boundary has a second entrance with a 6.3m wide wayleave through to Church Street, which is a wider street (9m at site entrance). This second entrance could be used as an access point for large machinery and for delivery of materials and equipment onto the site.
The basement is excavated by using permanent embedded retaining walls formed using concrete secant piles around the perimeter and excavating the soil in between. The secant piles remain as a structural component of the building. The basement floor slab is cast-in-situ with integrated pad foundations to support the cast-in-situ columns supporting the ground floor slab which is also cast-in-si...

...s possible with steel more so than other methods.
7. Long term retention of strength properties
8. Does not burn
9. Is not vulnerable to insect or fungal attack
The structure of this building was designed with a number of criteria in mind. First and foremost, the client would require speedy construction in order to generate income. This resulted in the use of structural steel for the majority of the building above grade.
The existence of a basement carpark resulted in the use of concrete as part of the structural makeup of the building. Concrete was also used structurally in the cores and floor slabs for its fire resistance and tensile and compressive strengths.
In conclusion, the combination of both materials in this project was deemed appropriate as the aim was to utilise the advantages of both steel and concrete in the design of the building.

- Introduction Makeup setting spray is a technologically advanced mist that comes in a bottle with a spray nozzle attached to it. It can be bought with hypoallergenic qualities and has a wide variety of properties to fit all skin types. (Kassi, April 26, 2014) Most mists claim to hold makeup in place for 16 hours. (Sephora, 2014) Makeup setter is said to work by using temperature control technology to keep the heat away from the skin by absorbing the moisture from the skin and slowly evaporating over the course of 16 hours....

- Introduction Animal testing has continued to be used throughout the makeup industry, with over 200 main stream brands actively testing on animals (PeTA, 2012). Some of which include prestigious brands such as Clinique, Elizabeth Arden and Lancôme. The need for change comes as animals are continuously being exploited by these large companies. For all the testing of cosmetics and toiletry products on animals has been banned in the UK, laboratories that use mice, rats, birds, reptiles and amphibians are exempted from the minimal protections under the Animal Welfare Act (AWA)....

- ... The viscoelastic behaviour of a stiff material such as GFRP can be recorded in a stress-relaxation test, by subjecting the test specimen to a sudden strain and keeping this strain constant for the duration of the test. This was done in the second test which was based on ASTM E328-02(2008), ‘Standard Test Methods for Stress Relaxation Tests for Materials and Structures , and returned the Young’s modulus of the material as a function of time, E(t). A static axial clip-on extensometer of 25 mm gauge length and ±0.125mm accuracy (at gauge length) was used in both tests to measure the change in length parallel to the direction of the load applied....

- The moving wind towards the building turns aside making an overpressure on the exposed façade. The deviated flow separates at the corner from the building creating a turbulent boundary layer. Vortex shedding appear as oscillating flow from opposite sides of a structure and engender fluctuating load perpendicular to the wind direction. Structural vibrations may occur due to resonance effect when the frequency of vortex shedding matches the natural frequency of the structure. Therefore, the Eurocode 1991-1-4 should not be used for buildings taller than 200m and very slender or unusual structures because it does not provide regulation on the following aspects: wind actions on lattice towers w...

- Structural Engineering and Ethical Decision Making INTRODUCTION Currently in the state of California, designers employed in the building industry follow the 1997 Uniform Building Code (UBC 97). The UBC 97 is intended to be a minimum requirement for both engineers and architects to follow in the design of any structural building or bridge. There are exceptions to the use of the UBC; local jurisdictions have the right to adopt other codes for there use. For instances some counties or cities may adopt certain ordinances that go beyond the UBC.... [tags: Structural Engineering Essays]

- Introduction D+ was the grade that the ASCE gave to America’s infrastructures in their 2013 Report Card. This grade is assigned based on eight criteria: capacity, condition, funding, future need, operation and maintenance, public safety, resilience, and innovation. According to the grading scale used, the infrastructures are in “poor to fair condition and mostly below standard, with many elements approaching the end of their service life” . Although it is a slight improvement from the last Report Card, this grade shows that America’s aging infrastructures are failing to keep pace with the current needs of the country....

- An Analysis of The Building Larkin put "The Building" in the middle of his collection for a reason, it is a pillar that supports the rest of the collection with its long lines and many verses, and because of this, is maybe a bit more clearer than some of his other poems in the ideas and views that are expressed through it. Of course, being a Larkin a poem, there is the obligatory underlayer which so many people miss, but in "The Building" it is easier to discern and comprehend. The title of the poem, "The Building" already hints at the main theme of the poem.... [tags: The Building]

- Today technology allows us to construct structures that we would never have been able to make in the past. Some of the creations are impressive based on what they accomplish but others are masterpieces in themselves. Man’s capability to build such tall buildings, as the skyscrapers we are familiar with covering our cities today, is a major expression of the advancements we have made as a culture. The power necessary to build such tall structures inspired competition between architects to see who could build the tallest one.... [tags: Architecture Structure Building Essays]

- The Hyundai commercial caught my attention due to its interesting plot. It seems to be a typical car advertisement until you look at it with deeper thought. The situation reveals something totally opposite of what they actually meant to do. Hyundai may have known exactly what they were doing, putting an advertisement out there that would not be easily forgotten. However the impact of this message can be an extremely negative image for Hyundai. The image they end up portraying can cause extremely negative publicity or send people the wrong message....
