Need help with my writing homework on Preliminary Design and Analysis of an Exhibition Centre in Hyde Park. Write a 1250 word paper answering; The framing of the building generally uses a combination of composite beams alongside open-web steel joists which are primarily supported using trusses. Additionally, it uses heavy long-span girders in various locations where trusses are not permitted. The deflections of the floor as well as vibration have as well been accorded significant concern and utilized a concrete slab of thickness 3-1/2 inches.

The braced steel frames offer a lateral load resistance for the dissipation of seismic energy. In order to arrange braces for the large format truss structure, the structure used truss load paths both for vertical and lateral loading. Nonetheless, there was little option for lateral brace usage. Through the strategic selection of locations for lateral resistance proportional to the mass of the building, the system is balanced in line with the building mass and hence minimizes torsional motion associated with the building.

The distribution of both dead and dynamic loading is considered. The dead load basically considers the weight of the roof. On the other hand, seismic and wind loading are considered in the analysis of the loading conditions to which the building is to be subjected. Seismic action effects are evaluated taking into account the presence of all gravity loads displayed in following action combination (Ajaya, 2010):

Just like is the case in calculations, earthquakes show a more extreme effect on the building as compared to wind. There is no visible deformation resulting from the wind effect. Rather these effects conform to quantitative analysis findings and remain negligible. See the table for details.

The results indicate that the building is self-sufficient. Sap2000 analysis confirms most of the results revealed by manual calculation. Based on all the results, it is evident that response spectrum analysis results compare well to the manual results obtained. Nonetheless, sap2000 analysis results show slightly higher values as compared to the manual. This is probably explained by varying CQC combination from the sap 2000 analysis.&nbsp.&nbsp.

Hello, I am looking for someone to write an article on The Immigration. It needs to be at least 1500 words.

Settlements concentrated in areas with sizeable industrial activity such as New York, New Jersey, and Pennsylvania. Immigrants with intentions of farming preferred Midwest or Great Lakes states. 1960-2010 saw the integration of immigrants, for instance, through the significant increase of arrival of African immigrants at will. Mexicans currently top the list of 21st-century immigrants to the United States. However, European immigrants make up more than 15 percent of America’s total immigrants each year in the 1960-2010 periods.

Push and pull factors:

Social: a history of immigrants in the U.S was particularly crucial in influencing immigration. This is because immigrants prefer to move in with already established relatives and friends in the U.S. for instance, most Jews chose to settle in New York in the 19th century, and this trend remains the same in the 20th and 21st century.

Geographic positioning: it is crucial to note that transport was tiresome and unreliable during the 1820-1920 period. Therefore, migration was subject to proximity to the U.S. Most immigrants were from Europe because it is close to the U.

S. however, the change from sailboats to steamboats made transport faster and more convenient. Steamboats also led to immigrants’ ability to move in and out of America quickly, therefore, reducing the chances of them permanently settling in the U.S. There were even movements in the 1900’s such as the Eugenics movement that discriminated against immigrants, not from North Europe, like Mexicans and southern immigrants because they were inferior races. Eugenics also influenced the passing of the Immigration Restriction Act of 1924.

1960-2010: advanced technology and fast means of transportation favor immigration. Proximity no longer tops the list as a pull factor for immigrants.

&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Laws: In the 1920s, immigration policies had prejudice tendencies, unlike in the 21st century, and this discouraged immigration of specific nationalities. There are various acts set up as of 1921 that have restricted immigration, for instance, the Quota act. Other actions include the 1882 Chinese Exclusion Act.

The 1965 Immigration and Nationality Act is not biased against a nation (Organization of Americans 15).
