某五层重点设防类建筑，采用现浇钢筋混凝土框架结构如图所示，抗震等级为二级，各柱截面均为600mm×600mm，混凝土强度等级C40。
假定，三层平面位于柱KZ2处的梁柱节点，对应于考虑地震作用的基本组合剪力设计值的上柱底部的轴向压力设计值的较小值为2300kN，节点核芯区箍筋采用HRB335级钢筋，配置如图所示，正交梁的约束影响系数ηj=1.5，
框架梁。试问，根据《混凝土结构设计规范》（GB50010—2010），此框架梁柱节点核芯区的X向抗震受剪承载力（kN）与下列何项数值最为接近（）
A．800
B．1100
C．1900
D．2200
参考答案：D
解析：
根据《混凝土结构设计规范》11.6.4条规定：
=2243×103N
关键是hb0值的计算，取两侧梁截面有效高度的平均值。
A young man was one day taking a walk with a professor. As they went along, they saw 36 in the path a pair of old shoes. They guessed the shoes belonged to a poor man who had 37 finished his day’s work in a field close by. The student 38 the professor, saying, “Let’s play the man a(n) 39 : we will hide his shoes, and we stay behind those bushes to see his 40 when he cannot find them.” “My young friend,” answered the professor, “we should never 41 ourselves in that way. You are 42 , and may give yourself a greater pleasure by helping the poor man. Perhaps we put a 43 into each shoe, and watch his reaction.” The student did so, and they both 44 themselves behind the bushes. The poor man soon finished his work, and came 45 the field to the path where he had left his coat and shoes. While 46 his coat he slipped his foot into one of his shoes; but feeling something 47 , he bent down to feel what it was, and found the coin. He was 48 , and looked at the coin again and again. He then looked around 49 on all sides, but no person was to be seen. He now put the money into his pocket, and began to put on the other shoe; but his surprise was 50 on finding the other coin. His feelings overcame him; he fell upon his 51 , looked up to heaven and preyed, He spoke of his wife, sick and 52 , and his children without bread. The timely giving, from some unknown hand, would 53 from dying. The student was moved and his eyes filled with tears. “Now,” said the professor, “are you not much better pleased than if you had played your 54 trick?” The youth replied, “Thank you! Sir! I feel now the 55 of those words, which I never understood before: ‘It is more blessed to give than to receive.’
