Purpose To minimize risk of coastal communities arising from cyclones, several risk mitigation initiatives have been taken in countries. Cyclone shelters have proven to be an important critical infrastructure in saving lives from cyclones. A large number of coastal critical infrastructure in the form of multi-purpose cyclone shelters (MPCS) are built to provide safe shelter during disasters. Often observed, such critical infrastructures are non-operational during the normal period, which makes them difficult to use during any disaster. Efforts have been made to keep these infrastructures in working condition. This research paper aims to bring together various management practices adopted for the MPCS in the South-Asian region with a focus on Bangladesh, and India. It also suggests ways to improve these practices for sustainable management of the MPCS. Design/methodology/approach India and Bangladesh are the most vulnerable countries in the South Asian region. As per the Global Climate Index, India and Bangladesh come in the list of “in extreme risk” countries in the world and are vulnerable to several natural hazards, especially climate-induced hydrometeorological hazards. India has a vast coastline and out of 7,516 km of coastline, a large extent, i.e. 5,700 km is prone to cyclones and that keeps 40% of the population vulnerable living within 100 km of the coastline. On the other hand, Bangladesh has a coastline of 580 km, which is equally vulnerable to tropical cyclones. Safeguarding communities from impending coastal risk through coastal cyclone shelters are of prime concern. This paper uses a qualitative approach to analyze secondary data, and literature in the field of critical infrastructure, sustainability, cyclone shelter, and management practice for cyclone shelters. Findings To provide sustainability and community ownership of the MPCS, various service plans are adopted in different countries. This paper provides insights on service and sustainability efforts made for the proper functioning of the MPCS in India and Bangladesh. It also provides insight into the roles played by different institutions involved in maintaining the MPCSs. Originality/value The research reiterates understanding of the cyclone shelter management from different geographic locations in the South Asian region. Various gaps identified in shelter management practices are discussed in the paper and key recommendations are proposed for better management of cyclone shelters.

Reinforced concrete is a global material, the utilization of which has no limits. India is a country that uses mostly RC framed structures as the routine building construction type. The building is made of inter-connecting elements in horizontal and vertical directions. To showcase the effectiveness of high grade of concrete and confining reinforcement much research has been carried out till date from 1980s. However, in design of structures we do not consider the effect of confining reinforcement in resisting stress in any member element. Various tools have been developed to find the capacity of member at element level to resist forces. For performance-based design of buildings, it is necessary to evaluate the performance at individual local level and at global levels. In this study, the effect of available tools (for section analysis) and design codes for member limit calculation is demonstrated and structure is evaluated for the threshold limits given in ASCE-41. It is observed that the code designed members are sufficient to resist lateral earthquake forces effectively for the estimated hazards if proper design tools are employed.
