1、2004-11-6 15:51:16原提问
在集中标注处为4根25螺纹,原注位为8根25螺纹在计算时集中标注的4根钢筋是否也为单跨锚固计算,如果是的话后面详图和前面的说明是否矛盾.
陈青来教授回答：梁下部钢筋通常不采用集中标注，如果采用，则先注上部通长钢筋，在“；”号后接注下部通长钢筋。如果集中标注了梁下部通长钢筋，又在原位标注，则原位标注取值优先（取代集中标注的同类筋）。
陈达飞先生回答： 1、“原提问”有一个问题：集中标注的“4根25螺纹”为下部通长钢筋，是否也是按“单跨”在中间支座锚固？
    2、人们通常有一个看法，即：集中标注的下部通长钢筋是贯穿通过中间支座，而原位标注的下部钢筋是在中间支座锚固。这样的认识对不对？
    3、如果相邻跨的同一规格的下部钢筋都在中间支座锚固的话，这必

1,2004-11-6 15:51:16 original question
Mark Office in the concentration of 25 to 4 threads, the original note for the eight 25-bit thread in the calculations focus on the four tagging single-span steel anchor is also calculated, and if so in front of the back of the note details and whether the conflict.
Professor Chen Qinglai answer: the lower part of steel beams are usually not marked by concentration, if used, then the upper part of the first injection through a long steel bar, in the ";" was followed by injection through the lower part of a long steel bar. If the concentration of the lower pass mark of the long steel beam, but also in situ labeling, the in situ labeling of priority values (instead of labeling the same concentration of bars).
Mr. Chen Dafei answered: 1, "the original question," There is a problem: centralized marked "4 25 thread" as the lower part through a long steel bar, whether it is by "single-span," bearing anchor in the middle?
    2, people often have a view that: focus on the bottom marked by a cross-cutting through the middle of a long steel bearing, and in situ labeling of the lower part of bearing steel is in the middle of Anchorage. This understanding right?
    3, if the neighbor across the lower part of the same size bearing steel anchor in the middle of it, this will
