In order to find out the dynamic characteristics of a steel frame structure project in the 8 degree (0.3g) area, the artificial wave, Taft wave and El Centro wave were input by using the finite element analysis software ANSYS. The dynamic time-history analysis of the structure shows the dynamic performance of the structure under the frequent earthquakes and rare earthquakes.

In this study, indoor quality and environmental comfort were investigated in secondary school buildings located in the State of Kuwait. Comfort variables such as temperature and relative humidity (thermal comfort), noise (acoustic comfort), illumination (visual comfort), as well as allocated classroom floor area per student (spatial comfort) were measured. Data was collected over a 7-month period on a spot basis during school hours in student-occupied classrooms at 46 selected schools. The measured data was then compared to international guidelines and standards related to indoor environment quality. The data for noise and allocated space were shown to be in the comfort ranges in all the schools. However, 11% of the schools are not adequately illuminated, 33% had temperatures not within the recommended limits, and 22% of the schools had humidity levels either higher or lower than the recommended levels. Also, 9% of the schools had low illumination readings.In addition, during the data monitoring, a survey was conducted by which the student occupants completed a questionnaire so that subjective and objective evaluations could be compared. The findings of the questionnaire displayed significant correlations between the measured data and some ailments and other complaints experienced by the students.Ultimately, the results found in this research will provide a baseline for comparison with future indoor environment quality assessments in buildings. Furthermore, recommendations are suggested in order to improve the environmental quality problems encountered in some of the schools, which may be beneficial for policymakers, facilities managers, and design engineers.

In the past 30 years, China has experienced development at full speed, andthe cities have expanded rapidly. There have been dozens of megacitieswith millions of people. Due to the lack of preparation of various factors,these cities will inevitably also have some urban diseases similar to thosein the mega-cities of the world. How to develop mega-cities, especiallyhow to ensure the sustainable development of mega-cities, such as Beijing, Shanghai, Guangzhou, etc., is a question that must be answered. Thispaper mainly discusses the challenges faced with city planning, especiallyfor mega-cities, taking Beijing as an example and analyzes from following aspects: institutional challenges, demographic challenges, and environmental challenges, and hopes to provide references for city planners

The green belt, located on the outskirts of a metropolis, has many characteristics such as good location, better landscape environment than urban areas, high availability in an original environment, low development costs and large and concentrated open spaces. With the huge population in China, this has led to a shortage of green space per capita and the shortage of recreational space. In view of such conditions, the recreational function of the green belt is very important, and can compensate for the shortcomings of tight urban recreation space. However, there has always been an important question about the scientific aspects and rationality of green belt use and control measures. In this paper, some outcomes of the Chinese green belt policy will be introduced. Then, three advantages and two disadvantages will be shown. Finally, reasons analyse and comparisons between China’s main cities and cities with a successful green belt will be given.
