【简答题】
The International Committee of the Red Cross says it will need nearly $ 650 million to help victims of armed conflict and violence next year. The Geneva-based ICRC runs humanitarian operations in some 80 countries. 1. The International Committee of the Red Cross has operations in just about every trouble spot in the world, including Afghanistan and the Palestinian territories. 2. However, it says it will have to expand its operations even more next year because of the deteriorating situations in those countries. The director of ICRC Operations, Pierre Krahenbuhl, says his agency has been running regional operations for West Africa out of Ivory Coast for years and, there fore, is in a good position to expand its programs there. Mr. Krahenbuhl says the Red Cross has been carrying out assistance and medical projects, as well as visiting prisoners held by the government and the rebels. 3. The Red Cross says Afghanistan remains its largest and costliest operation. However, is adds that it has cut more than $ 40 million off year's budget due to the improved situation in that country. Cuts also have been made in programs for Sri Lanka, Sierra Leone and Yugoslavia.

【简答题】根据以下资料,回答17~18题。 有一现浇钢筋混凝土框架结构,受一组水平荷载作用,如图3-1所示,括号内数据为各柱和梁的相对刚度。由于梁的线刚度与柱线刚度之比大于3,节点转角θ很小,它对框架的内力影响不大,可以简化为反弯点法求解杆件内力。顶层及中间层柱的反弯点高度为1/2柱高,底层的反弯点高度为2/3柱高。 已知梁DE的MED=24.5kN·m,试问,梁DE的梁端剪力VD(kN),与下列何项数值最...
