Vehicle collision is occurred in the ground level of buildings accidentally or intentionally. This event is a common scenario of generating structural damages. In some cases, these damages usually have not been retrofitted. Therefore, these initial damages influence on the future behavior of buildings under natural events. In this regard, it is necessary to investigate the performance of buildings with such initial damages during future earthquakes. In this paper, the collapse capacity and endurance duration of steel moment-resisting frame (SMRF) structure with one corner damaged column due to light vehicle impact has been evaluated under seismic excitations. For this aim, an intermediate SMRF with 5-story is modeled in OpenSees software two-dimensionally. Then, the initial damage scenarios are considered with 3 states. The first scenario without considering a damaged column and scenarios 2 and 3 are assumed to have a corner damaged column due to vehicle impact with velocities 60 and 120 km/h, respectively. Moreover, the numerous nonlinear incremental dynamic analyses (IDAs) have been performed under 14 pairs of far-fault earthquake records up to the dynamic instability of the models. Afterwards, fragility curves are utilized in order to specify the collapse capacity and endurance duration of SMRF in three defined scenarios for different performance levels. Finally, the effect of having a corner damaged column is evaluated under selected earthquakes. The obtained results indicated that scenario 3 had a weaker performance compared to other scenarios during seismic records. For instance, in a statistical level of 50%, the values of seismic collapse capacity in scenario 3 is decreased 17% and 41% compared to scenarios 2 and 1, respectively. Also, the new findings showed that endurance duration of scenario 1 was greater than other scenarios. It is increased 28% and 77% versus scenarios 2 and 3, respectively.

在建筑物的地面意外或有意发生车辆碰撞。此事件是产生结构性损坏的常见情况。在某些情况下，通常不会对这些损坏进行翻新。因此，这些初始损害会影响建筑物在自然事件下的未来行为。在这方面，有必要调查在未来地震中具有这种初始损坏的建筑物的性能。在本文中，钢瞬间崩溃的能力和耐力持续时间-抗帧（SMRF由于光车辆碰撞与一个角部损坏的列）结构已根据地震激励进行评价。为了这个目的，以5层的中间SMRF为模型OpenSees软件二-三维。然后，将初始损坏场景考虑为3种状态。不考虑损坏列的第一种情况以及假设情况2和3分别由于车辆以60 km / h和120 km / h的速度撞击而具有转角损坏列。此外，大量的非线性增量动态分析（的IDA）已下进行14成对的远-断层地震记录多达车型的动力不稳定性。此后，利用脆性曲线来指定其的崩溃能力和耐久性持续时间。在三个定义的方案中，针对不同的性能水平的SMRF。最后，在选定的地震条件下评估了柱子拐角损坏的影响。获得的结果表明，与地震记录期间的其他方案相比，方案3的性能较弱。例如，在统计水平为50％的情况下，与方案2和1相比，方案3中的地震倒塌能力值分别降低了17％和41％。另外，新发现表明，方案1的耐久时间比其他方案长。分别增加28％和77％分别与方案2和方案3相对。
