Structural Resilience of RC and Masonry Buildings

5 April 2023

In this two-days webinar organized by the UNESCO Chair in DRR&RE at UCL, we will discuss the structural resilience of Reinforced Concrete (RC) and Unreinforced Masonry (URM) buildings. We will focus on retrofitting design and good practice examples across different countries

This is a 2-day course on structural resilience against seismic hazard. The course will introduce the fundamentals of retrofitting design based on the most accepted international codes. Common RC and URM building types will be presented and the type of damages that these building types in experienced in previous earthquakes will also be discussed.

On Day 2, different techniques for retrofitting will be presented for each typology, emphasizing the type of deficiency that is targeted to be improved. A number of retrofitted buildings that have shown good performance in recent earthquakes will be examined. The audience are encouraged to participate in discussions and Q&A throughout the course.

Rohit K Adhikari, PhD

University College London

rka

Rohit Adhikari is a Research Fellow within the UNESCO Chair in DRR-RE at UCL. He has obtained a PhD in Structural Earthquake Engineering from UCL with a focus on structural classification, numerical modelling and seismic analysis, fragility and vulnerability assessment as well as risk reduction measures for masonry school typologies. He has worked in the GPSS program of the World Bank in developing the GLOSI library. He has participated in disaster risk assessment projects on school infrastructure in several countries including El Salvador, Dominican Republic and Nepal. During these engagements, he has carried out field survey of school facilities in several countries, has participated in capacity building and knowledge transfer activities. Currently, he is working in the SFRES-Nepal project that aims to develop an assessment methodology for both the structural safety and functional adequacy of school infrastructure.
