Dynamic Response of an End-Supported Pontoon Bridge due to Wave Excitation: Numerical Predictions versus Measurements

Figure 10

Estimated -conditional probability density functions for peak period and peakedness factor. Both plots are based on fitting a lognormal distribution to the data points The data used are restricted to having a good fit to the JONSWAP spectrum, i.e., with . Furthermore, a linear fit to the ridge of the probability density function is computed and shown in the plots. This fit is based on the subdomain of the probability density function, where  m. (a). The fitted equation reads out . The Pierson–Moskowitz (denoted PM) relation between peak period and significant wave height is also given. The data points are indicated by dots. (b). The fitted equation reads out .
