Masonry, the most commonly used building typology is the building of structures from individual units, which are often laid in and bound together by mortar. Masonry structures are the most vulnerable with external forces. Nepal is disaster prone zone and get frequently attack by various hazard such as earthquake, wind storms, flash-floods, fire, landslides, heavy rain fall, lightening and many more. So, in order to maintain resistive structures, seismic vulnerability of structure should be examined. Nepal Population and housing Census 2011, total 3350143 (2,397,441 –Mud bonded bricks/stone and 952,702- Cement Bonded bricks/ stone) houses out of 5423297 (61.77%) are found to be have masonry foundations. So, to link the context of Resistance structures in Nepal’s context first of all, the predominating stone masonry spread widely over Nepal must be checked for their seismic vulnerability. So, a typical residential stone masonry building is taken for this study. Seismic Vulnerability of the Building is examined in accordance with guidance provided by Government of Nepal- Ministry of Physical Planning and Works, 2011 in their guideline which describe the procedure for qualitative and quantitative assessment of structural earthquake vulnerability of public and private buildings in Nepal. Furthermore, Building is modelled and analyzed by using ETABS software. The outcome obtained from ETABS software are used to find the condition of building and to propose method for its strengthening.

This paper presents a review of the methods for seismic vulnerability assessment, together with an experimental method based on shaking table testing. This method is applied to a Portuguese masonry building typology with stone walls and timber floors, subjected to increasing earthquake damage. Traditional-like materials and techniques are used in the building. The vulnerability curves are presented and the damage indicator is correlated with the crack patterns and EMS 98.

Traditional art of building in Bosnia and Herzegovina comprises brick or stone masonry structures. Most historical buildings belonging to national cultural heritage were made of stone-masonry. The country is situated in seismic active region of South-East Europe. In the case of strong earthquake motion such buildings could suffer heavy damages. Some structural elements of historical buildings, as domes and arches, cracked already by moderate earthquake but without the loss of stability. Substantial damages were caused by recent war disaster. Damages could be accumulated through the history as well. Generally, stone-masonry buildings in Bosnia and Herzegovina can be classified in vulnerability classes between A and C according to European Macroseismic Scale. Design and construction procedures for rehabilitation are presented here with examples of repair and strengthening of mosques, which present historical stone masonry structures dating from the Ottoman period in Bosnia and Herzegovina. Traditional and contemporary materials were used for their rehabilitation. It is important to preserve original forms, especially those of damaged elements. The challenge for structural engineers and architects was to find equilibrium between aesthetical and structural demands.

Before And After

The present paper aims at inspecting the structural behaviour of a typical masonry aggregate located in the historical centre of Cercola, a municipality in the province of Naples. The clustered building under study consists of four structural units mutually connected to each other made of tuff stone and deformable floors. Two distinct structural units, namely in heading and intermediate places, in both isolated and aggregate conditions, are examined to estimate the influence of structural positions on the global seismic response of the examined case study buildings. For this purpose, non-linear static analyses are performed using the 3MURI software. Pushover analyses are conducted to both evaluate the seismic behaviour of examined structural units and improve their earthquake performances while considering proper retrofit interventions on vertical and horizontal structures. The analysis results are plotted in terms of risk factor, stiffness, and ductility. Finally, a set of fragility functions are derived to point out the structural response of the case study buildings before and after retrofit interventions. From the achieved results, it is highlighted that retrofit interventions improve the structural performances of the buildings, especially those of structural units in aggregate conditions.
