月见草

这是我上高中时,住在寄宿宿舍那年夏末的事情。容易醒来是刚开始睡在寄宿宿舍二楼那会儿。被睡相不好的邻舍男孩欺负吵醒,时钟才指向四点多,夜里,打开一半的明晃晃的寝室玻璃窗亮起了曙光,睡眼蒙眬地,还觉得是在并列吊着的蚊帐中,做着新的旧的黄绿色的梦。窗户的下框处可见扁柏高高的树梢,从那上面,好像刚睡醒的后山在窥视着。     

哥特式教堂中彩绘镶嵌玻璃窗的盛行原因分析

本文从＂创作方＂和＂审美方＂两个方面谈了哥特式教堂中彩绘镶嵌玻璃窗的盛行原因,＂创作方＂包括美学思想以及建筑、玻璃制造业两方面,审美方则是指当时社会的主流审美观念。最后得出的结论,哥特式教堂中彩绘镶嵌玻璃窗的盛行是这两方面原因相辅相成的结果,缺一不可。     

亲爱的,我竟忘了那么多

高一的宿舍门再次被我推开——写着"鬼屋"二字的白纸落在桌上;窗外铁架上的衣服被风从这一头吹向另一头,像可笑的怪物;4号床铺枕头下的课外书露出一角……而她们,已坐在床铺上等我多时。浅蓝色的蚊帐被风吹起,划过她们的脸。她们都微笑地看着我。我也一一回以微笑,想起曾经的许多。萍,我不怨你在高中毕业后对我的躲避与误解。相反,我依旧常常想起你红扑扑的脸蛋和天生卷曲的头发。你那么     

台风为我贺生日

2007年9月18日星期二暴风雨9月18日是我的生日,正当我打算好好庆祝自己的八岁生日时,广播里却传来强台风紧急警报。"丁零零……"急促的电话铃响了,我一听,爸爸说晚上要值(zhí)班,不能回家了。     

Risk Assessment and Optimisation of Blast Mitigation Strategies for Design and Strengthening of Built Infrastructure

A probabilistic risk assessment procedure is developed which can predict risks of explosive blast damage to built infrastructure, and when combined with life-cycle cost analysis, the procedure can be used to optimise blast mitigation strategies. The paper focuses on window glazing since this is a load-capacity system which, when subjected to blast loading, has caused significant damage and injury to building occupants. Structural reliability techniques are used to derive blast reliability curves for annealed and toughened glazing subjected to explosive blast for a variety of threat scenarios. The probabilistic analyses include the uncertainties associated with blast modelling, glazing response and glazing failure criteria. Damage risks are calculated for an individual window and for windows in the facade of a multi-storey commercial building. The paper shows an illustrative example of how this information, when combined with risk-based decision-making criteria, can be used to optimise blast mitigation strategies.
