This study presents empirical ground-motion models (GMMs) for estimating Arias intensity (IA), cumulative absolute velocity (CAV) and significant ground-motion duration (D5–75 and D5–95), calibrated on Iranian strong motion database. The dataset consists of 1749 (with two horizontal components) acceleration motion time-series originated from 566 events with moment magnitude (Mw) 3–7.5 range and recorded at 338 stations in the distances range up to 200 km. Common functional forms were adopted for all four models to facilitate easy comparison of derived model parameters and model predictions. Residual distributions and their unbiased variation with predictor variables Mw, hypocentral distance (Rhypo), time-averaged shear-wave velocity in the top 30 m (VS30) indicated robustness of the derived models. This study also examines residual correlations between different pairs of ground-motion intensity measures (GMIMs). The correlations were analysed separately for between-event (δBe\documentclass[12pt]{minimal}
