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。 相似文献

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。 相似文献

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。 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

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? 相似文献

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. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

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. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献
