To identify the reasons for the deformation of the purlins and eliminate potential safety hazards, a comprehensive structural inspection was carried out on this factory building, the inspection results indicate that the sectional dimension deviations of the measured steel components and the strength of the steel are in line with the design and code requirements. However, the mid-span deflections of some purlin components fail to meet the code requirements. The bearing capacity of the suspended loads under different working conditions was analyzed: Among the 9 hanging load working conditions of the purlins, the bearing capacity of the purlins in 4 working conditions did not meet the code requirements;among the 2 hanging load working conditions of the main frame, the bearing capacity of the frame beam components in 1 working condition did not meet the code requirements, and the deflections of the frame beams in both 2 working conditions did not meet the code requirements. In response to the above results, practical and feasible treatment suggestions were put forward.展开更多

Upon on-site examination, it was discovered that the connection (or node) construction mode of the building was correct. Only local surface flaws were present, and the operation was normal. The stress wave velocity of the randomly inspected wooden columns with surface cracking was close to the critical velocity, suggesting that no obvious cavities or decay defects existed within the measured wooden components. Based on the inspection outcomes, finite element computations were carried out for the wooden structure, arriving at the conclusion that the maximum stress value of the wooden members was smaller than the designed value of wood strength, and the vertical bearing capacity conformed to the requirements of the specifications. And rationally offered relevant treatment suggestions, providing a reference for the inspection and identification of such projects.展开更多

文摘In China,the oversupply of coal occurred in 2009,and from that year onwards,China’s coal economy began a low-carbon and clean transformation.Evaluating transformation performance is the research goal of this paper.The data collection for this paper includes data on deep processing of Chinese coal products from 2009 to 2020,as well as data on asset structure evolution and financial performance of 34 listed companies in the Chinese coal mining.Entropy value method is used to calculate the entropy value of low-carbon transformation,and the regression analysis is used to study the performance of cleaner transformation,the conclusion is as follows:(1)From 2009 to 2020,in China’s total energy consumption,coal consumption accounted for 71.6%in 2009 and 56.8%in 2020,the goals set by the state have been achieved.(2)The national goal of reducing the proportion of coal consumption and reducing carbon emissions has forced the transformation of deep processing of coal products.The transformation of coal enterprises towards low-carbon and clean production has achieved remarkable results.(3)From 2009 to 2020,the non coal industry income of 34 listed companies in China’s coal mining industry increased by 8.21%annually.At the same time,the asset structure was adjusted,and nearly 80%of the asset structure evolution showed an orderly development trend.(4)The regression analysis results show that the entropy value of coal deep processing products and the entropy value of asset structure adjustment are significantly related to transformation performance.The paper proposes to summarize the successful experience of China’s coal energy economic transformation,lay a foundation for achieving the carbon peak and carbon neutral goals in the future,further increase the intensity of coal deep processing,increase the proportion of clean energy in total energy consumption,and strive to control asset operation towards the goal of increasing the proportion of non coal industry income.
文摘This paper explores the Major National Dialogue organised by Paul Biya from the 30th of September to the 4th of October,2019 as a panacea to the Anglophone.The paper also seeks to find out if this dialogue has been the panacea Cameroonians as a whole and the people of Southern Cameroons in particular have been waiting for to end this conflict.This research uses a qualitative research design.This is because the researcher culled information from Jeune Afrique Economie(2019a),Cameroon Tribune,and from Phoenix.Descriptive analysis was used to analyse the collected data.Descriptive analysis is used to get the views of the public whether the Major National Dialogue was really a panacea to the Anglophone crisis.The analysis revealed that there were two opposing opinions on the holding of this dialogue.The government thinks the dialogue was a panacea to put an end to this crisis because there is ongoing construction work in the war zones,and economic activities have witnessed an increase in the regions as the various production units of the Cameroon Development Corporation(CDC)and Pamol plantations have regained agricultural activities.The Ndawara tea estate now functions without problems.Trans-border trade is on the rise and transportation is fluid,except in the rural areas where the state of the road network is poor to name but these.On the other hand,politicians,political parties like the Social Democratic Front,activists,religious leaders,the affected populations,and Cameroonians at large think that the Major National Dialogue was a monologue and therefore was bound to fail because first,key actors arrested and detained in connection to this crisis were not part of this dialogue.For this reason,they are calling for a genuine and an inclusive dialogue.In addition,they argue that we cannot be talking of peace when fighting is still raging on and people are being killed,houses and schools are being burnt,and people are being kidnapped every day for ransom to mention but these.
文摘During the renovation process of a certain factory building, significant deflection deformation occurred in the purlins. To identify the reasons for the deformation of the purlins and eliminate potential safety hazards, a comprehensive structural inspection was carried out on this factory building, the inspection results indicate that the sectional dimension deviations of the measured steel components and the strength of the steel are in line with the design and code requirements. However, the mid-span deflections of some purlin components fail to meet the code requirements. The bearing capacity of the suspended loads under different working conditions was analyzed: Among the 9 hanging load working conditions of the purlins, the bearing capacity of the purlins in 4 working conditions did not meet the code requirements;among the 2 hanging load working conditions of the main frame, the bearing capacity of the frame beam components in 1 working condition did not meet the code requirements, and the deflections of the frame beams in both 2 working conditions did not meet the code requirements. In response to the above results, practical and feasible treatment suggestions were put forward.
文摘This article takes the inspection and appraisal of a certain migratory wooden structure as the backdrop, presents the inspection process of the wooden structure. Upon on-site examination, it was discovered that the connection (or node) construction mode of the building was correct. Only local surface flaws were present, and the operation was normal. The stress wave velocity of the randomly inspected wooden columns with surface cracking was close to the critical velocity, suggesting that no obvious cavities or decay defects existed within the measured wooden components. Based on the inspection outcomes, finite element computations were carried out for the wooden structure, arriving at the conclusion that the maximum stress value of the wooden members was smaller than the designed value of wood strength, and the vertical bearing capacity conformed to the requirements of the specifications. And rationally offered relevant treatment suggestions, providing a reference for the inspection and identification of such projects.
