建筑防震设计的新思维

现行的建筑抗震规范以“抗”为主，为了满足抗震的要求，往往受材料强度的制约。不得不对房屋高度作出限制。这对对少人多的我国是很大的浪费。而且抗震不减震，仍不免室内设备的破坏，造成经济上巨大损失，以隔震为主要形式的减震设计则可以解决这一矛盾，本介绍了抗震建筑与减震建筑的主要概念，我国隔震试点工程的概况，并对今后的隔震研究提出了建议。

现行的建筑抗震规范以“抗”为主.为了满足抗震的要求,往往受材料强度的制约,不得不对房屋高度作出限制.这对地少人多的我国是个很大的浪费,而且抗震不减震,仍不免室内设备的破坏,造成经济上巨大损失.以隔震为主要形式的减震设计则可以解决这一矛盾.本文介绍了抗震建筑与减震建筑的主要概念、我国隔震试点工程的概况,并对今后的隔震研究提出了建议.     

框架隔震建筑设计方法及算例

基于《建筑抗震设计规范》(GB50011—2001)的有关规定，为方便工程技术人员了解和掌握隔震技术的应用，以框架结构为例，详细介绍其隔震设计方法和步骤。     

建筑物抗震隔震和减震的探讨

在进行建筑物抗震设计时,一定要遵循《建筑抗震设计规范》提出的抗震设计原则和抗震设计构造要求进行设计,正确应用计算机软件,提高建筑结构设计质量,而且还要加强概念设计。使用功能有特殊要求的建筑以及抗震设防烈度为8、9度的建筑等可采用隔震和消能减震设计。采用隔震或消能减震设计的建筑,当遭遇到本地区的多遇地震影响、抗震设防烈度地震影响和罕遇地震影响时,其抗震设防目标应高于相应未采取隔震或减震的建筑。

隔震技术的应用及发展

随着隔震技术的发展,隔震技术已经从研究领域进入到实际应用阶段。国际、国内已经采用隔震技术的建筑到4000栋左右。因此,人们开始研究当地震来临时,怎么减震、消震、减弱地震能量。隔震技术开始应用于建筑中,在过去的几十年中,经过历次地震检验,隔震设计的建筑,耗散地震能量效果显著。隔震技术是近几十年来地震工程最重要成果之一,是一种经济、可靠、有效的防震减灾技术,因此世界各国都在研究抗震减灾技术,致力于提高建设工程的抗震设防水平,提高建设工程的抗震能力。     

浅谈工程抗震隔震技术

本文简要回顾了我国地震灾害情况及传统抗震结构与隔震结构的设计思路的不同，阐述了隔震结构的基本原理。然后从安全性、适用性、经济性和灵活性四个方面全面地阐述了隔震结构有别于传统抗震结构的优点，并据此及国内外资料和隔震技术的当前发展状况认为，隔震技术的发展前景不可限量。     

建筑结构隔震技术的发展及应用

相对于传统的抗震技术,建筑结构隔震技术能够更有效的防止建筑物被地震破坏,确保人民的生命财产安全。     

利用隔震技术的连续刚构桥结构振动特性

以某公路大桥为工程背景，探讨隔震技术在连续刚构桥中的应用。首先建立非隔震和隔震结构纵向地震反应分析模型，通过有限元理论对两种结构进行时程分析，结果表明隔震的连续刚构桥具有较好的抗震能力。     

浅谈日本建筑抗震设计

汶川大地震之后,中国建筑师重新对建筑抗震设计重视起来。通过介绍了日本建筑结构抗震新技术、新材料和严格的建筑结构设计要求,并介绍了日本建筑应用抗震设计的实例。希望建筑师从我国高层建筑抗震设计现状出发,有效地借鉴日本抗震新技术,从而推动我国防震抗震减灾事业的蓬勃发展。

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
