Infill walls are masonry walls constructed to fill the gaps between the structural frames. In structural analysis, these walls are considered non-structural members as they do not participate in the load transfer mechanism. These walls offer considerable resistance in terms of a diagonal strut when the bounding frame experiences lateral loads. This...

The World Stress Map is a global compilation of data on crustal stress designed to assess worldwide stress patterns and identify stress sources. However, its effectiveness is limited due to inadequate coverage in Africa. This research project aimed to model crustal stress patterns and understand the correlations with contemporary seismicity. To thi...

Studying the patterns and characteristics of seismic activity and crustal deformation in Africa is vital for understanding the geodynamics and predicting seismic hazards in the region. By understanding the deformation characteristics, scientists can help mitigate the risk of earthquake-related disasters in Africa. However, assessing deformations ha...

Diaphragm is a structural member of the lateral load resisting system. In this chapter, rigid diaphragm is compared with semi-rigid diaphragm of 25% and 50% flexibility in a rectangular plan model by providing slab openings. The slab openings around 1–2% is considered in this study with openings at center and corner locations. Response spectrum ana...

The Horn of Africa is considered as one of the seismically active regions on the African continent because of the Main Ethiopian rift system, one of the most active rift systems within the East African rift system. Therefore, it is essential to continuously analyze the seismicity to assess seismic hazards in a region of interest. To this end, seism...

Earthquake is one of most destructing threat which cause severe damage to life and property. Recently, due to increasing demand and need for the present generations has made the designers and engineers to plan for structures having irregularities. It is impossible to avoid designing uneven buildings in reality. It is important to research how this...

Background The initial phase of earthquake hazard assessment involves the consolidation of diverse magnitude scales, thereby requiring the homogenization of various magnitudes. Moment magnitude (Mw) emerges as the preferred descriptor for a range of magnitudes, encompassing local magnitude (ML), teleseismic magnitude (e.g., mb and MS), duration mag...

The objective of the present study is to estimate of service life of reinforced concrete structural members subjected to chloride-induced corrosion of steel reinforcement. Based on the review of literature, a procedure for service life estimation of reinforced concrete structural elements has been identified. Though the procedure used in this thesi...

The African continent is one of the few tectonic plates where very few earthquakes have been reported. Sporadic poor data have jeopardized efforts to assess seismic hazards. In light of the tectonic setting, a review of the continent’s seismicity is crucial for predicting seismic hazards. For this study, seismicity data from USGS and ISC catalogs w...

This paper explores a new method to model and forecast the global earthquake energy release time series. The ISC-GEM catalogue of global events with magnitude Mw≥6.4 is used in this study. The magnitudes of individual events are converted into seismic energy using an empirical relation. The annual earthquake energy time series is constructed by add...

This article explores a new strategy for forecasting of earthquake energy release in the seismogenic zones of the world. A total of 41 active seismogenic zones are identified with the help of past seismicity data. The magnitudes of individual events occurred in each zone are converted into seismic energy using an empirical relation. The annual eart...

In this article, a study on development of ground motion prediction equations (GMPEs) is undertaken for seismically active regions in India. To derive the equations, the seismically active regions are divided into four units based on seismotectonic setting and geology. Due to lack of strong motion data, a stochastic finite-fault simulation method i...

In this article, a stochastic finite fault source model is calibrated to estimate ground motion in northeastern India for intermediate depth events originating in the Indo-Burmese tectonic domain. A total of 47 three-component accelerograms from eight events with magnitudes ranging from M w 4.8–6.4 are used to estimate the input source and site par...

This article simulates the ground motion during the devastating 18th September 2011 Sikkim earthquake by analytical approaches. Surface level peak ground acceleration (PGA) values at several stations in the epicentral region have been estimated by the finite fault seismological model. A PGA contour map in the epicentral region is provided. It is fo...
