- 中文摘要：
本文旨在研討如何預估預力混凝土梁之失效概率，並用一系列之例題，說明如何使用實用印度規範（Indian Code of Practice）及美國混凝土協會規範（Code of American Concrete In-stitute），以設計梁之失效概率。預鑄梁時，須以基本材料之各項可能之強度為隨機變數，此項變數，應符合規範之規格。而梁之失效概率，可由確定之公式求得之。吾人發現，預力混凝土梁之失效概率，對鋼筋之變動極為敏惑，而受混凝土強度之影響則較小，此點應予注意。
- 英文摘要：
The prediction of probability of failure ofprestressed Concrete beams is presented in thispaper, and probability of failure of beams design-ed by Indian Code of Practice and Code ofAmerican Concrete Institute is illustratedthrough a set of examples. Probable strengthof basic materials used in the beam are genera-ted as random variables subjected to code spe-cifications and the probability of failure of thebeam is obtained through explicit formulation.It is found that probability of failure of pre-stressed concrete beam is very sensitive to va-riation of steel and less sensitive to the variationin the strength of concrete. We should pay at-tention to this.
