Evaluation Of A Substitute Structure Method To Estimate Seismic Displacement Demand In Piers And Wharves, Rakesh K. Goel May 2018

Evaluation Of A Substitute Structure Method To Estimate Seismic Displacement Demand In Piers And Wharves, Rakesh K. Goel

Civil and Environmental Engineering

This paper compares seismic displacement from the MOTEMS and the ASCE/COPRI 61-14 substitute structure method (SSM) with results from the nonlinear response history analysis (NLRHA). It is found that the SSM is biased toward overpredicting displacement demand for short-period systems and under-predicting displacement demand for long-period systems. The overprediction was found to be excessive for very-short period systems (i.e., systems with periods shorter than the period at which the design spectrum transitions from linearly increasing spectral acceleration to constant spectral acceleration). It is recommended that the SSM not be used for such systems. It is also recommended that the SSM …


Seismic Forces In Ancillary Components Supported On Piers And Wharves, Rakesh K. Goel May 2018

Seismic Forces In Ancillary Components Supported On Piers And Wharves, Rakesh K. Goel

Civil and Environmental Engineering

This paper presents a simple procedure to estimate seismic forces in ancillary components (secondary systems) supported on marine structures such as piers, wharves, and marine oil terminals (primary systems). Since many such marine structures can be idealized as single-degree-of-freedom (SDOF) systems, this study uses a simple linear-elastic model with two DOF, one representing the marine structure and the other representing the ancillary component. This study shows that acceleration at the base of the secondary system is approximately equal to spectral acceleration at the fundamental period of the primary system. It also proposes a formula, which is an improvement over current …

Site Response Analysis Considering Strain Compatible Site Period, Hoss Hayati, Robb E.S. Moss Nov 2016

Site Response Analysis Considering Strain Compatible Site Period, Hoss Hayati, Robb E.S. Moss

Civil and Environmental Engineering

In practice it is common to estimate site effects using a single proxy, or single variable such as 30 m shear wave velocity (VS30) or site period. Many studies have investigated merits of proposed proxies with contradicting recommendations. Yet, most studies indicate the single proxy approach is less than ideal, resulting in large uncertainty. To provide a better understanding of components that drive site response, we performed a parameterized study on 19 shallow soil profiles with VS ranging from 150 m/s to 400 m/s. We propagated 74 input motions through each soil column using one-dimensional equivalent-linear …

Nonparametric Liquefaction Triggering And Postliquefaction Deformations, J. S. Yazdi, Robb Moss Sep 2016

Nonparametric Liquefaction Triggering And Postliquefaction Deformations, J. S. Yazdi, Robb Moss

Civil and Environmental Engineering

This study evaluates granular liquefaction triggering case-history data using a nonparametric approach. This approach assumes no functional form in the relationship between liquefied and nonliquefied cases as measured using cone penetration test (CPT) data. From a statistical perspective, this allows for an estimate of the threshold of liquefaction triggering unbiased by prior functional forms, and also provides a platform for testing existing published methods for accuracy and precision. The resulting threshold exhibits some unique trends, which are then interpreted based on postliquefaction deformation behavior. The range of postliquefaction deformations are differentiated into three zones: (1) large deformations associated with metastable …
