Experimental Research and Numerical Analysis on the Law of Deteriorated Performance for R.C. Frame Structure with Seismic Damages under Elevated Temperature (part II)
The cracks were pre-settled to the R.C. frame structure caused by earthquake which was defined as the damage index ω during the modeling process with analysis software-ANASYS. The temperature field contour curve were calculated for the column and beam, the law of deteriorated bearing capacity with time for the R.C. frame structure under elevated temperature were brought forward,which can adapt to R.C. frame structure with different damage index ω caused by earthquake.The relationship between ω and deteriorated bearing capacity for R.C. frame structure was also given, which was proved to be effective and correct according to comparison with the data recorded from the elevated temperature experiment designed by author.</jats:p

The numerical solution of waveguide discontinuity problems
A computational method for solving a wide range of transverse and longitudinal waveguide discontinuity problems is described. Results are obtained by the simultaneous solution of matrix equations, generated by Fourier analysis, which relate the complex amplitudes of orthogonal electric and magnetic field components. In some cases the solution is found to be sensitive to the way in
which infinite series of field functions are truncated, and it is shown how the optimum form of truncation can be determined for many configurations of practical importance.
Several examples showing the application of the method are
given, and comparison of results with those obtained by experiment, and by other analytical techniques, confirms its accuracy.
The application of the method in the design of discontinuities for higher-mode generation in multimode antennas is considered, particularly in connection with a multimode monopulse feed for a satellite-communication reflector antenna. Primary and secondary characteristics are determined theoretically for various modeconverter
configurations, allowing those giving satisfactory allround
performance to be selected. Comparison with conventional
feeds shows the multimode feed to be superior in many respects. A prototype multimode feed is constructed, and theoretical primary radiation patterns are compared with those obtained experimentally
