| Abstract: | In the local compression formula, the calculating area used in checking local compression bearing capacity to the results has a great impact. How to reasonably layout pre - stressing tendon, so that the calculating area used in checking local compression bearing capacity is max in the limited cross-section is the main point of this article and give out the reasonable arrangement of three - beam, six - beam and seven - beam and its local compression area formula for calculating area used in checking local compression bearing capacity. |
