钢结构旧厂横向刚度的实测计算及其可靠性鉴定标准的探讨

在《工业厂房可靠性鉴定标准》中，如何按空间图形评定厂房的横向刚度，尚缺乏标准。在太钢第一炼钢厂平炉车间抽柱钢厂房的可靠性鉴定中，采用按空间工作的实测法和空间计算模式的有限元分析进行了评定，并根据研究结果提出了建议标准     

论建筑的同一性和多样性

西方建筑发展历程充满了复杂性和矛盾性，而造成这种现象的主要原因就是因为它们的建筑设计思想缺乏本质同一性的统摄。     

当前云南水泥行业面临"四难"

一是销售难,致使水泥大量积压,不得不限产、停产.往年进入四季度是水泥销售旺季,去年普遍旺季不旺.据业内人士分析,原因之一是总量过剩.云南250多家水泥厂,年生产能力约2200万吨,近几年实际产量1600万吨左右,国家经贸委下达云南的控制数2001年是1500万吨.在供大于需的市场环境中,竞相压价,有的低到一百五六十元一吨就出手.某县有两个不同所有制的水泥厂,按正常价比,两厂竞相压价每年少收入2000多万元,笔者建议县里成立个销售公司,统一价格,一致对外."市场经济行不通."难道市场经济就可以不顾成本恶性竞争吗?原因之二是各级政府换届,该上的项目还顾及不上.这一点不具有普遍性,根本原因还在于总量过剩(主要指传统工艺的量过剩、新型于法量占的比重还很小很小).原因之三是一些地方的保护政策、优质水泥难进到该进的市场.     

物境·情境·意境——川中“龙”镇罗泉景观解析

“枯藤老树昏鸦,小桥流水人家,古道西风瘦马,夕阳西下,断肠人在天涯”,“西风残照,汉家陵阙”,“木末芙蓉花,山中发红萼。涧户寂无人,纷纷开且落”……中国古诗为我们描绘出一幅幅情景并茂、内容丰富的精美画面,千古流传。中国诗画同源,追其源头,不外乎是诗人、画匠对现实世界优美景象的抽象与升华,触景生情、有感而发的佳作罢了。唐代诗人王昌龄就诗的创作有过精辟论述:诗有三境:一曰物境。欲为山水诗,则泉、石、云、峰之境,极丽绝秀者,神之于心,处身于境,视罗泉“九宫一寺八庙”是按照“龙”的形态进行布局,旨在说明图腾崇拜,同时也是罗泉…     

What can be taught in architectural design? — <Emphasis Type="Italic">parti,poché</Emphasis>, and felt qualities

This essay begins with a reflection on what has been taught in architectural design since the turn of the twentieth century. I shall trace back to the two disciplinary foundations of the French École des Beaux-Arts — parti and poché — in the education of an architect in the eighteenth and nineteenth centuries. I shall then attempt to superimpose parti and poché on a modern disciplinary framework, say that of mathematics, which leads to musings on a series of architectural problems that include pattern versus type, stability versus mobility, orthogonal versus oblique, confinement versus transparency, and aging versus metallic sheen. These paradoxes, I suggest, demand the education of an architect to address both the instrumental pattern of a building configuration and the ambient felt qualities of a room, rather than vision alone.     

小城镇发展规模研究--以天津市为例

小城镇的合理发展规模 城镇合理规模主要指在一定的历史时期内,根据城镇的性质和具体条件、科学技术、生产力和经济水平,从低消耗、高效率、有利生产、方便生活,达到良好的经济、社会和生态环境效益而制定的规模。一般用两个指标进行衡量,一是人口规模,二是用地规模。     

Spatial competition and regulatory change in the grain handling and transportation system in western Canada

The grain handling and transportation system (GHTS) has been a defining component of the western Canadian economy since the early part of the last century. Only two major railways serve the grain handling industry, so the potential for the exercise of market power in transportation appears to be significant. In fact, spatially oriented regulations applicable to railways exist in Canada to mitigate this, but to date they have not often been used by shippers. While the reasons for this are not completely clear, we suggest that the regulations are now inadequate for the current state of the GHTS. Using a unique data set from the year 2000, we assess the effect on the grain handling industry of modifications to these regulations, and find that significant gains for shippers from these modifications are possible. These gains are computed to be on the order of C$10–15 million per year for grain shippers alone. We would like to thank conference and presentation participants (Transportation Research Board, Canadian Agricultural Economics Society, University of British Columbia, University of Leeds and California State University, Long Beach) as well as the anonymous reviewers who commented on the earlier versions of this paper. We would also like to acknowledge support from the Saskatchewan Department of Highways.     

让水泥窑成为市政设施的重要一环

在中国建筑材料联合会换届大会上,联合会面向全行业提出了"宜业尚品、造福人类"的发展新目标。这一目标的提出,符合党的十九届五中全会精神的要求,契合了国家远景目标,是国家发展目标在建材行业的具象化和具体体现,富有新意且意义深远。水泥生产是以石灰石、黏土等为原料,煤炭作为燃料煅烧并添加其他混合材而成的一种胶凝材料。第一次产业革命,催生了硅酸盐水泥的问世。     

如何发挥建设单位在安全生产管理中的作用

在国家基础建设过程中,工程质量、进度、成本控制三大目标的实现是建立在安全生产的基础之上的,脱离了安全生产特别是防火、防触电、防高空坠落、防土方坍塌等安全措施的保障,就不能充分保证三大目标的实现。一般情况下,施工安全生产管理工作由承建商负责,建设单位不必直接参与安全生产管理工作,但在实际管理中,一旦建设单位积极参与建设工程安全生产管理工作,必将对进一步促进工程质量、进度、成本三大控制目标的实现产生重要的推动作用。下面,我就建设单位如何做好建设工程安全生产管理工作谈一下个人看法。1在招标文件中规定统一的安全生…
