Gempa merupakan salah satu yang terjadi akibat kejadian pergeseran tiba-tiba dari lapisan tanah di bawah permukaan bumi. Purwokerto sebagai kota Kabupaten Banyumas adalah kota yang saat ini berusaha berkembang seperti halnya kota-kota besar lainnya yang ada di Indonesia. Gedung perkuliahan merupakan fasilitas pelayanan umum dalam hal pendidikan terhadap masyarakat Sebagai gedung perkuliahan harus mampu memberikan kelayakan dan kenyamanan sehingga aktivitas di dalam dan luar gedung perkuliahan menjadi nyaman. Penelitian ini bertujuan meninjau kerentanan beberapa bangunan yang terdapat pada Universitas Wijayakusuma terhadap gempa bumi. Untuk mengetahui kelayakan bangunan tersebut pendekatan analisa yang dilakukan dengan menggunakan metode RVS yang terdapat pada FEMA 154, selain itu perhitungan pembebanan dilakukan dengan pemodelan SAP 2000 dengan metode 3D Response Spektrum. Hasil penelitian menunjukkan bahwa gedung bertingkat pada Universitas Wijayakusuma Purwokerto aman terhadap gempa apabila dikaji dengan metode RVS, sedangkan apabila dikaji dengan metode 3D response spectrum yang sesuai dengan SNI 1726-2019 gedung-gedung tersebut kurang aman untuk waktu getar alami fundamental, tetapi untuk pembebanan ketiga gedung tersebut aman.

Landslides are the biggest threat in the Kalirejo area. The dynamics of land movements in the mountains often cause cracks and potentially collapse. Landslides due to land fractures caused building damage. This study aimed to analyze the condition of a simple building on the influence of land fracture. The method used was conducting a field survey of existing buildings in the Kalirejo area. The data of the surveys were the percentage of building damage and building categorization. From the results of the analysis, the percentages of buildings in the safe category were 78 buildings or 54.17%, the buildings of the unsafe category were 51 buildings or 35.42%, and buildings with the unsafe category were 15 buildings out of 144 surveyed building with the percentage of 10.42%. Based on the results of the analysis using the Rapid Visual Screening (RVS) method, 15 buildings with unsafe conditions need to be relocated because they do not use the minimum structure required for simple buildings while the 51 buildings with unsafe conditions, repairs must be made to the structure according to the minimum requirements of simple buildings

Historic buildings of Nepal are mainly constructed from masonry structure. Since masonry structures are weak in tension which leads to the failure of structure. So, to avoid possible damage in environment lives and property it is urgent to conduct vulnerability assessments. Seismic vulnerability of historic masonry buildings constructed in Bhaktapur at Byasi area is carried out for the case study. Five load bearing masonry buildings were selected out of 147 buildings considering opening percentage, storey and type of floor for modeling in SAP 2000 V10 Various methods of rapid visual screening (FEMA 154, EMS 98) are used to determine the vulnerability of the selected building. The Selected Building response is carried out by linear time history analysis. The seismic vulnerability of masonry structures is determined in terms of fragility curves which represent the probability of failure or damage due to various levels of strong ground motions for different damage state slight, moderate, extensive and collapse. From the result of Rapid Visual Screening (RVS) and Fragility curves of the buildings it is found that whole, buildings are found vulnerable from future earthquake.
