In the present work, a probabilistic seismic hazard analysis has been performed for the newly formed Warangal Urban District, Telangana, India. The standard Cornell–McGuire method has been adopted considering different seismic zones. The area of influence chosen is having a radius of 500 km with NIT Warangal as the centre. An earthquake catalogue for the period 1800–2016 AD has been compiled and homogenized using global empirical relationships. Alternative models have been considered for seismic zoning scenario, completeness analysis of earthquake catalogue, maximum magnitude and ground-motion prediction equations (GMPEs) in the logic tree approach by assigning normalized weighs to each model, thereby reducing the epistemic uncertainty. Seismic hazard has been presented as the peak ground acceleration (PGA) and pseudo-spectral acceleration (PSA) maps at 5% damping for spectral periods T = 0.05, 0.1, 0.5 and 1 s at 2% and 10% probability of exceedance in 50 yrs period. The results obtained were compared with IS: 1893-1 (2016) (Criteria for earthquake resistance design of structures, Part-I. Bureau of Indian Standard, New Delhi, 2016) and NDMA (2011) (Development of probabilistic seismic hazard map of India, Technical Report of the Working Committee of Experts (WCE), National Disaster Management Authority (NDMA). Govt. of India, New Delhi, 2011) and they were found to be in excellent agreement. The profile of shear wave velocity (V_S) was obtained by using the multichannel analysis of surface wave (MASW) method. The site was characterized as per NEHRP manual based on V_S. The obtained shear wave velocity values are used in performing the 1-D ground response. A higher PGA has been observed at surface level when compared with the PGA values obtained at rock level suggesting seismic wave amplification due to subsoil condition.

拟议中的智慧城市瓦朗加尔的特定地点概率地震灾害评估

在目前的工作中，已经对印度特兰加纳邦新组建的Warangal市区进行了概率地震灾害分析。考虑到不同的地震带，已经采用了标准的康奈尔-麦奎尔方法。选择的影响区域以NIT Warangal为中心，半径为500 km。已使用全球经验关系编制并统一了公元1800-2016年的地震目录。通过将归一化的权重分配给每个模型，已在逻辑树方法中考虑了其他模型用于地震分区方案，地震目录的完整性分析，最大震级和地震动预测方程（GMPE），从而降低了认识上的不确定性。T = 0.05、0.1、0.5和1 s，在50年内出现概率分别为2％和10％。将获得的结果与IS：1893-1（2016）（结构抗震设计准则，印度标准第I部分局，新德里，2016）和NDMA（2011）（开发概率地震危险性图）进行了比较。印度，国家灾害管理局（NDMA）专家工作委员会（WCE）的技术报告，印度政府，新德里，2011年），并被认为是非常一致的。通过使用表面波的多通道分析（MASW）方法获得了剪切波速度（V _S）的轮廓。该站点根据基于V _S的NEHRP手册进行了表征。所获得的剪切波速度值用于执行一维地面响应。与在岩石水平获得的PGA值相比，在表面水平观察到了更高的PGA，这表明由于下层土壤条件引起的地震波放大。
