“…Subsequently, Bravo-Haro and Elghazouli (2018) introduced two functional forms to obtain estimates of maximum interstory drift, IDR max , demands from their maximum residual interstory drift, RIDR max , demands counterparts based on the seismic response of steel moment-resisting frames. More recently, Ruiz-García and Ramos-Cruz (2020) proposed a new power functional form for estimating IDR max from RIDR max demands for steel moment-resisting frames subjected to near-fault earthquake ground motions having forward-directivity effects.…”

A discussion on the article by Quinde et al. is presented. The methodology introduced by the authors is based on residual displacements computed from the inelastic response of elastoplastic single-degree-of-freedom systems subjected to synthetic ground motions representative of those recorded at soft soil sites in Mexico City. While the subject to the article is pertinent for post-earthquake assessment, this discussion points out and clarifies several issues about residual displacement demands and their estimation based on previously published investigations by the discussers.

“…However, at higher IMs, certain stories show decreased θ res at increasing seismic intensity, denoting recentring behaviour. This behaviour occurs because in the higher IMs, the weak response cycles in the early stages of vibration are scaled up so that they are strong enough to yield the frames and hence alter their behaviour [10,19].…”

“…This difficulty is also one of the reasons that the maximum transient drift is more commonly used as an Engineering Demand Parameter (EDP), as it requires less computational work, even though it happens temporarily in the earthquake event and can only be measured by a continuous structural health monitoring that is quite rare. Several predictive models of residual drift have been developed and are available in past studies (e.g., Ruiz-García and Guerrero [9], Ruiz-García and Ramoz-Cruz [10], Arab and Yakhchalian [11]). However, these models were either built for a certain type of ground motion, soil, or special steel structures, which makes them hard to generalise and compare.…”

The seismic permanent or residual drift is a structural response parameter of relatively easy collection and one whose usefulness in damage assessment has been proven in many past earthquake events. Oftentimes, residual drifts are a key factor when deciding on the demolition of a number of structures, even if said structures do not show other evident signs of severe damage. However, general studies on seismic residual drift demands are far less common than those dealing with its transient maximum drift counterpart. In this paper, we offer a simple data-driven predictive model for residual drift demands in Steel Moment Resisting Frames (SMRF). To this end, our model is based on a database generated by nonlinear response history analyses (NRHA) on 24 deteriorating SMRFs under the action of 596 hazard-consistent ground-motion records resulting in a database of more than 14 000 structural responses. The model development is preceded by an extensive feature selection process that employs several Machine Learning (ML) algorithms. Importantly, all available seismic codes and studies regarding residual drift demands available to date have overlooked the issue of hazard consistency, therefore disregarding the causal connection between seismic hazard level and the corresponding ground motion suite used. In contrast, we use the Conditional Scenario Spectra method, which generates a set of realistic earthquake spectra with an assigned rate of occurrences based on their spectral shape and intensity, hence, our results preserve the critical relationship of hazard consistency. In this context, our model highlights the severe over- and under-estimations associated with hazard-inconsistent estimates of residual drifts.

“…Subsequently, Bravo-Haro and Elghazouli (2018) introduced two functional forms to obtain estimates of maximum interstory drift, IDRmax, demands from their maximum residual interstory drift, RIDRmax, demands counterparts based on the seismic response of steel moment-resisting frames. More recently, Ruiz-García and Ramos-Cruz (2020) proposed a new power functional form for estimating IDRmax from RIDRmax demands for steel moment-resisting frames subjected 44 to near-fault earthquake ground motions having forward-directivity effects. (2) We find the literature review on the estimation and prediction of residual displacement demands of structures built on soft soil of Mexico City particularly incomplete.…”
