Comparative Study of Pile Supported Wharf Structure Including Soil Structure Interaction Effects Using Nonlinear Static Pushover Analysis
Ports and harbors are considered as lifeline structures because of the significant role they play in transporting people and cargos cost effectively. A large number of important ports are located in active seismic regions worldwide. Currently in India, no guideline is available for seismic design of Port structures and hence performance analysis of such structures becomes essential. A typical pile supported wharf at Mundra Port, Gujarat (Latitude: 22º43′88″ N, Longitude: 69º42′34″ E) is selected for the study (Shah and Shah in J Struct Eng 43:235–246, 2016). In this study, analysis and design of existing pile supported wharf structure for different loads and load combination using depth of pile fixity and with considering linear spring as per IS code. Capacity curves are derived for an existing pile supported wharf with considering depth of pile fixity as per IS code guideline and using nonlinear soil spring model using p–y, t–z, and q–z curve. The wharf is modeled using nonlinear platform along with soil structure interaction. Pushover analysis is performed to obtain its capacity curve with nonlinear plastic hinge formation. Based on the peak responses of the piles, PIANC has recommended qualitative criteria to judge the degree of damage to a pile supported wharf. But quantitatively, PIANC does not specify the bound for each damage state. Hence upper bounds of the damage states I, II, and III are based on the sequence of plasticity development in the pushover process (Shah and Shah, Int J Res Eng Technol 7(6):16–27, 2018). It is observed that without considering soil structure interaction, results are overestimate based on design and capacity curve.
