随着工业化速度的不断加快,传统建筑方式已经不适合当下建筑行业的发展,而混凝土浇筑也无法真正实现建筑工业化,进而装配式建筑应运而生。而填充墙影响着整体框架结构的抗震性能、承载力及刚度等等,是装配式建筑可持续发展的必然内容。本文主要探究装配式混凝土填充墙对框架结构抗震性能的影响,并分析混凝土填充墙的高宽比及各项影响框架结构抗震性能的因素,综合分析混凝土填充墙发框架结构的承载力及刚度,为装配式混凝土填充墙建设提供参考。 相似文献

Eliminating poverty is a multifaceted global challenge and a focal point of global development governance. With the implementation of targeted poverty alleviation (TPA), China's poverty alleviation efforts have had significant achievements. This study provides a new perspective by classifying poverty-stricken households based on poverty root causes at the household level, a multi-propensity score weighting model based on counterfactual inference is employed to examine the poverty reduction effect and policy precision on six non-equivalent poverty-stricken household groups in a Chinese county. The results reveal that the poverty reduction effects differed among poverty-stricken households with different root causes of poverty. Specifically, households impoverished due to disability have the lowest income of the six groups. The assistance policy effects also vary significantly and are found to be poorly suited to poverty-stricken households a lack of labor force and funds. A robustness test confirms this conclusion and a more nuanced analysis reveals that these differences are reflected in the wage and transfer incomes. Therefore, to ensure the stability of poverty reduction and the sustainability of income for poverty-stricken households, relevant associated aid policies need to place different emphases based on their household characteristics. 相似文献

This article is first to model energy poverty in Chinese households using an Engel curve approach. To analyse the determinants of energy poverty and energy expenditures across households, we avail the 2015 wave of the Chinese General Social Survey (CGSS). Possible presence of endogeneity is accounted for in the model specification as well as by using the Lewbel heteroscedasticity identified endogenous variables estimator. In addition, we are the first to scrutinise disparity and discrimination by conducting the Blinder–Oaxaca decomposition of energy poverty model by gender, ethnicity, region (Eastern vs. non-Eastern provinces), and urbanisation status (rural vs. urban residents). Our analysis shows: (i) education is the key determinant of various energy poverty measures and energy expenditure shares across Chinese households; (ii) other determinants including fossil fuel mix and electricity price discrimination are found to worsen energy poverty, on average. However, fossil fuel mix is found to increase expenditure share of total energy, electricity, and coal and decrease that of biomass; and (iii) the Blinder–Oaxaca decomposition analyses show no statistically significant gender or ethnic discrimination in energy poverty rates. However, there is substantial divide between Eastern and non-Eastern provinces and between rural and urban households—with these groups also discriminated against when accessing clean cooking fuels and technologies. The Blinder–Oaxaca results also generally support the logistic and the Lewbel energy poverty model findings. 相似文献

Record levels of domestic and global stimulus during the COVID-19 pandemic years helped to mitigate largely unparalleled downside risks. Post-COVID-19, inflation surged in Australia due to overseas factors such as the war in Ukraine, and domestic factors such as COVID-related backlogs in the construction sector. To constrain inflation, the Reserve Bank shifted to a phase of aggressive monetary policy tightening in 2022. There are, however, cost of living ramifications associated with tighter monetary policy. Looking forward, there is significant uncertainty about the rate at which inflation will normalise, and the spending response of consumers to higher interest rates. 相似文献

It is generally accepted that cultural differences affect individuals' approaches to ethics, but how are the effects of culture manifested in perceptions of ethics? Further, how are cultural differences displayed in such ethics-related actions as recommendations for business ethics education? Managers' responses from two starkly different cultures, China and Iceland, reveal, somewhat surprisingly, that one group's top business ethics concerns and business ethics education recommendations are at the bottom of the other group's rankings, and vice-versa, yet each appears reasonable given the cultural background. This shows how nuanced the expression of cultural differences in the realm of ethics can be and how potential practical steps may rely on perceived “top” ethical issues. Together, these findings imply that there is more to explore about the role of culture on ethical reasoning and behavior than researchers have examined to date. We provide suggestions for further research and practical applications. 相似文献
