Study on Assessment Method of The Quality of Building Structure Design

我国的建筑业跟着城市化进程的快速推进得到了飞速发展，社会对建筑美感的追求也不断增强，越来越多的高层、日益复杂的建筑造型和环境作用使结构设计的任务更加困难。结构设计的综合性较强，需要考虑的因素众多，而这些因素又是相互制约相互影响的关系。例如要满足复杂的建筑造型，但也要尽可能保证结构的规则性和安全等性能要求；确保结构具有足够刚度承受荷载的同时还要确保结构的延性设计；要尽可能地使结构经济但也要确保结构的安全适用等。虽然在近十年时间里，计算机逐渐普及和计算性能得到了飞速发展，让即使再小的设计院也能对高层结构甚至超高层结构进行计算，但我国结构设计质量的水平差距过大的现象并未有所缓解。最主要的原因还是设计...With the rapid advancement of urbanization,Chinese Construction Industry has developed at full speed.Because of the growing pursuit of architecture aesthetics,there are more and more high-rise buildings with increasingly complex architectural shapes which makes building structure design more difficult.Structure design is quite comprehensive which needs to consider many factors.However,interaction...学位：工学硕士院系专业：建筑与土木工程学院_结构工程学号：2532014115177

Research on Waste Cost Management Based on Lean Thinking

工业发展带来物质极大丰富的同时废弃物数量也剧增，随着环境问题的日益突出，环保法规逐步健全，执法力度不断提升，消费者环保意识日益增强，作为废弃物主要生产者的企业，面临越来越大的法律风险和市场压力。废弃物不仅严重污染环境，也造成了巨大的资源浪费，给企业带来沉重的负担。在资源稀缺、环境污染日益严重的今天，对废弃物及其成本进行有效的管理不仅有利于提高资源的利用效率，也有利于环境的保护，给企业带来经济效益和环境声誉。 本文站在企业的角度，将废弃物成本定义为企业因废弃物的存在并对其进行管理而发生的各种资源耗费，并将其划分为废弃物资源耗费成本、废弃物管理成本和废弃物损害成本。由于废弃物会造成资源浪费和环境...Wastes have dramatically increased while industrial development has brought prosperity. With the environmental issues become increasingly prominent, the environmental regulations improving and law enforcement continuing to strengthen, consumer awareness of environmental protection growing, enterprise, as the major producer of wastes, is facing more and more legal risk and market pressure.

明代闽中名臣马思聪生平、创作及影响

马思聪是明代福建名臣,官至南京户部主事,平生交游甚广,殉节于正德十四年(1519)宸濠之难。关于马思聪的史料记载零散且简略,学界相关专题研究甚少。通过考索各类正史、方志、族谱及其相关文献,能依次勾勒马思聪的生平,论断其配享风波。《马忠节父子合集》中保存了马思聪的诗歌24首,其诗风劲健昂扬,颇有唐诗风骨。其忠义气节影响了明清两代士人。考证马思聪的生平,不仅可补既往研究之未周,而且可以从一个侧面了解宸濠之难中明朝士大夫的忠义观念及行为实践

Oil pollution should belong to the underwriting objects of catastrophe insurance

油污符合巨灾保险承保对象所具有的损失发生巨大性、风险发生概率低、风险预测难度大和风险难以分散的识别标准,应属于巨灾保险承保对象。油污巨灾保险具有公共产品属性、石油利益的获得者具有广泛性、侵权损害赔偿责任呈现社会化分担趋势,故政府应当作为油污巨灾保险的投保人。将油污纳入巨灾保险体系中,有助于丰富油污保险类型,构建油污巨灾保险与普通油污保险二元并列的局面,以社会力量督促石油行业提高安全生产力度,并达到弥补普通油污保险、油污基金、政府救济等其他油污灾后救济制度缺陷的目标。Oil pollution conforms to the recognition standards of the underwriting objects of catastrophe insurance: huge loss, low probability of occurrence,difficult prediction and risk decentralization,therefore oil pollution should belong to the underwriting objects of catastrophe insurance.Considering that oil pollution insurance has the nature of public goods,the oil interests' gainers are widespread and socialization of tort liability,the government should be the applicant of oil pollution's catastrophe insurance.The establishment of oil pollution's catastrophe insurance is good to enrich the types of oil pollution insurance,establish the dualistic situation of oil pollution's catastrophe insurance and general oil pollution insurance,it enables the social forces to supervise the petroleum industry,and achieve the goal of remedying the limitations of other post-disaster relief systems,such as common oil pollution insurance,compensation fund and government relief.国家社科基金项目“海上钻井平台油污损害赔偿责任机制研究”(12BFX081

Study on the quality of structure design of the high-rise building

建筑设计质量的优劣决定了建筑施工质量的优劣和建造成本的高低,对建筑工程起着决定性的作用。研究表明,相对于建筑产品的全生命周期,设计成本可以少到忽略不计,但对建造成本的影响却高达70%~80%。文章主要从结构设计的各个阶段出发,探究了影响结构设计质量的重要因素,并结合工程实例探讨了正确处理各关键因素的重要性。方案设计阶段涉及结构体系、结构布置、构件尺寸和特殊技术措施等因素,结构计算阶段涉及模型的选取和计算、参数设置和计算结果的合理性判断等因素,施工图设计阶段涉及结构计算书和施工图绘制等因素。The quality and cost of building construction have been decided by the quality of building design which plays a crucial role in construction engineering. The results show that the design cost could be ignored when it comes to the whole life cycle of a construction product. However,70% ~ 80% of the construction cost is determined by the quality of design. This paper mainly introduced the major factors of structure design quality,and discussed the importance of correctly dealing with these key factors through an engineering project. The factors in scheme design phase include structure system,structure layout,the size of components and special technical measures. The factors in structure calculation phase involve the selection and calculation of structure model,the parameter setting and the judgment about the rationality of calculation results. The factors in construction drawing design phase refer to the calculation book and construction drawing plan

建筑设计质量评价方法思考

建筑设计是建筑施工的根据,低质量的建筑设计方案不仅影响建筑的施工质量,还严重影响着社会安全和公众利益。建筑设计质量的优劣决定了建筑施工质量的优劣和建造成本的高低,对建筑工程起着决定性的作用。文章主要总结国内外目前已有的建筑结构设计评价的方法以及国内在设计质量控制上的不足之处,分析建筑设计评价对于提高建筑工程质量和建筑产品投资效益的重要性,希望借此引起开发商和设计人员对结构设计评价与优化的重视,并结合国内实际情况提出相关建议

萘系高效减水剂的优化合成与改性

研究了工业萘系高效减水剂合成工艺的优化方案,得出了各合成阶段的关键工艺参数———时间、温度和原料用量的最佳控制值。尝试了一次性投酸法和用石灰代替液碱中和等新的工艺手段,前者可以简化合成工艺,但不会影响产品质量;后者不仅可以降低成本,而且所得产品除了用作减水剂,还可兼作加气混凝土的稳泡剂。对复合改性的研究发现,“萘系-糖钙”复合外加剂,既保持了显著的减水、增强效果,又达到了控制混凝土坍落度损失的改性目的

As a result, their reactions tend to afford cycloaddition intermediates or products. Herein, we report a reaction of M≡C and C≡C bonds that affords acyclic addition products. These newly discovered reactions are highly efficient, regio- and stereospecific, with good functional group tolerance, and are robust under air at room temperature. The isotope labeling NMR experiments and theoretical calculations reveal the reaction mechanism. Employing these reactions, functionalized dπ-pπ conjugated systems can be easily constructed and modified. The resulting dπ-pπ conjugated systems were found to be good electron transport layer materials in organic solar cells, with power conversion efficiency up to 16.28% based on the PM6: Y6 non-fullerene system. This work provides a facile, efficient methodology for the preparation of dπ-pπ conjugated systems for use in functional materials.This research was supported by the National Natural Science Foundation of China (Nos.
