In a method for retrieving sequences having a minimum PAPR in an OFDM (orthogonal frequency division multiplexing) system, by using characteristics in which all sequences of the OFDM system are classified into cosets having the same PAPR, PAPRs of sequences in which early two elements are fixed as '0' are calculated. A sequence having a minimum PAPR is selected from among the calculated PAPRs, and sequences allocated to the coset in which the selected sequence is included are retrieved as sequences having the minimum PAPR.

Then, safety analysis method was constituted considered the typical damage of concrete beam bridge. 5. By amending the reduction rate of loading capacity used in Code for Maintenance of Highway Bridges and Culvers (JTG H11-2004), a new reliable index is presented in the same safety standard to reflect the relation between load and resistance. According to the basic principal of calibration method, the recommended gradation index was computed under various factors such as different load combinations, vehicle operating status and different failure modes. With these calculated numerical values, the calculated reliability indexes standard for the estimation of safety degree of in-service concrete girder bridge members was ultimately obtained.6. Based on the related standards and results on crack and displacement that cannot continue to loading at home and abroad, the evaluation grade of the concrete beam bridge is proposed by analogy.
