This is a pushover analysis for pile‐supported wharves considering the dynamic magnification factors due to torsional effects. The piles seismic design by deterministic approach is shown accounting plastic hinges and P‐delta effects in 2D/3D mathematical modeling. A real structure placed at high seismicity area is considered as case study in order to validate the model and provide reliable technical data. New bound limits of seismic demands associated with damage states and the best soil performance are identified. A stochastic approach is proposed to estimate the no‐exceedance probability of horizontal displacements of a semi‐flexible with respect to a flexible model. Results are plotted in terms of base shears, displacements, and energy. The advantage of the use of pushover analysis in terms of displacements is estimated in 18–38%. Other results as bound limits, hysteretic damping, plastic rotation are compared with previous studies.

挠性和半挠性码头结构的推挤分析考虑了扭转效应引起的动态放大系数

这是考虑了扭转效应引起的动态放大系数的桩支撑码头的推覆分析。在2D / 3D数学建模中显示了通过确定性方法进行的桩抗震设计，考虑了塑料铰链和P-delta效应。为了验证模型并提供可靠的技术数据，将案例研究放在高地震活动区的真实结构中。确定了与破坏状态和最佳土壤性能相关的地震要求的新的界限。提出了一种随机方法来估计半挠性相对于挠性模型的水平位移的不超过概率。根据基础剪力，位移和能量绘制结果。在位移方面使用推覆分析的优势估计为18–38％。
