Steel slabs Global production

The world’s largest steel producers are China, Japan, and Ukraine, respectively, and there is fierce competition between countries in the global steel market. According to 2010 statistics, China accounted for 40 percent of global steel production that year. The biggest recession in the steel market dates back to 2008 and 2009. In the steel slabs , you will get to know more about the world’s steel producers.

The global steel and steel market is in the hands of China, Japan, and the United States, and China is far behind other countries. The growth trend of the steel market in 2013 was almost uniform, in 2008 the steel market faced many crises, but since 2010 it has overcome the existing crises and resumed its growing trend. According to experts, the steel market in the world will be in China’s possession for the next 100 years. According to published statistics, China accounts for about half of the world’s steel production. In 2014 and 2015, due to the widespread use of steel in industries such as construction, automotive, etc., China faced an increase in the consumption of steel products. In fact, China is the main market for steel production, but it has pledged to reduce its steel production by 2020, given warnings from the United States and European countries. You may be interested to know that there are about 40 open cases in Europe against Chinese products in various commercial sectors.

Global demand for steel slabs

Damage to structures is always inevitable. So far, many types of failures have been recorded in engineering structures with heavy casualties and financial losses. Therefore, identifying structural defects during operation to ensure safety at the lowest cost has been the subject of much research in the last two decades. In this regard, wave conversion, which is a powerful mathematical tool for signal processing, has attracted the attention of many researchers in the field of structural health monitoring. In this paper, due to the increasing expansion of steel shear walls in the construction industry, the issue of identifying the location of failure in steel plates was considered.

First, the steel plate was modeled and analyzed frequently with free support conditions in ABAQUS finite element steel slab dimensions, then the first eight shapes of the healthy and damaged modes were extracted. The shape of the primary and secondary modes was analyzed as a two-dimensional space signal by the conversion of a two-dimensional discrete wave. The results of the diagonal details of the waveform analysis of the secondary modes in comparison with the shape of the primary modes show more disturbance of the wave coefficients at the location of the failures. More suitable than wave coefficients with an error of less than 6% is revealed.
