3.0 Part B: Structural Frames 3.1 Portal Frame in Steel Function The function of portal frame in steel is to lower the load strength by distribute the loads from the super structure, and expansion it to a great area so that the strength of the load will not over the safe bear the weight of capacity. Special foundation measure hold back the distress in the super structure, due to expand or contract of the sub soil because of humidity movement in something matter of soils. Lastly, it offer provision of level surface, so that the super structure can be construct on top of the foundation. It can support loads from the super structure and transfer it to the ground. Material and Method used There are rarely ways applied to build a steel portal
According to scientist’s reports, global warming has been rapidly growing since the industrial revolution. In a speed that mankind is damaging the earth's ecosystem, the chance of the existence of several species, including human beings, is endangered. Comparing present day energy and fossil fuel energy, many of us come up with a result that present day energy is expensive. Nevertheless, if people consider the negative cost, which is caused by global warming, this result might be different. Various solutions like planting trees, and finding alternative energy resources might be helpful to fight global
Waves scour the bases of the wall and they often need maintenance or re-development 4. The availability of adequate drainage behind the wall is necessary 5. Modern recurved walls may promote coastline erosion since they do not hinder longshore drift but act as a mere barrier (Geography LWC, 2015) • Rip Raps Rip raps (also referred to as rock armours or boulder barriers) are large, heavy boulders of rocks strategically placed along coastlines which effectively dissipate wave impacts by absorbing its energy while significantly reducing the effects of erosion and impeding the movement of sediments. They essentially serve the same purpose as seawalls but are composed primarily of permeable structures. Rip raps are generally used in conjunction with other structures to fortify and further protect coastlands and is used mainly in this regard for extra fortification purposes or when finances are low and a quick and efficient structure is required for coastland protection.
My opinion on it is that it is clearly real and we need to do something to stop it. If we do not stop all of the pollution in this world, it can affect everyone 's way of living in the future. Global warming can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues.
The Problem: Global warming is influencing several parts of the planet. Global warming makes the ocean rise, what’s more the point when the ocean rises; the water covers numerous low territory islands. This may be a huge issue for many of the plants, animals and for the people living around the islands. Furthermore that water covers the plants and causes some of them to even die. The point is that when they die, those animals lose a source of food, alongside their habitat.
Let’s move to the summary that I mention the three effects before. The global warming can affect a lot to the earth that the polar ice caps is melting so that it will increasing the sea level and it going to flood in the cities in the pacific. The global warming are the cause of heatwave droughts so that it will rising the temperature and it will make the climate change. The last one is the global warming will change the ecosystem. Overall of this assignment, I have understood that our earth is "sick".
Coral reefs and sandbanks, however, had not been able to prevent the tsunami were completely, but only slow tsunamis at least it can mitigate the damage. Perhaps large structures or artificial reefs an option to counter the effects of the tsunami, but as we saw in Japan did not help them anyway when the tsunami 's force was larger than the structures could withstand. Overall, one should always be prepared for a tsunami and therefore build housing and other infrastructure that is more adapted to withstand tsunamis. One can not simply answer the question as it is both an issue of such resources, space and
What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem. The first question “What is Global Warming?” Global warming is the gradual increase of the temperature of earth 's atmosphere and oceans.
Now, I believe that global warming is bringing negative effect towards the world, and it accelerated the climate change, and it is continuing to cause dramatic fluctuation, this is a threat to us as human beings. Let’s take some serious problems that the global warming has caused: The melting sea ice in the Artic ocean that led to less platforms for the polar bears to hunt seals, resulted increase mortality of the polar bears. Another case will be the increase of droughts; it will bring famine (lack of crops), and results in limited supply of water, and animals will die because of the lack of plants. The climate experts projects that in 2100, the temperature will be at least 8 degrees warmer, even this small rise will have great consequences towards the whole ecosystem and living thing—including us. Above are all evidence and facts that are caused by global warming; I disagree with the thesis claiming that global warming is a hoax, apparently it is a serious problem that we need to draw more attention to, and to find the
