“…A few adobe houses were completely destroyed, many adobe and simple masonry buildings suffered significant damage (Figure 6 a). Also few masonry buildings with steel frame show moderate to substantial damage, an expected behavior (Moroni et al 2004). Two overpasses on the highway fully and another two showing minor structural damage.…”

Characterizing the local site response in large cities is an important step towards seismic hazard assessment. To this regard, single station seismic noise measurements were carried out at 146 sites in the northern part of Santiago de Chile. This extensive survey allowed the fundamental resonance frequency of the sedimentary cover, derived from horizontal-tovertical (H/V) spectral ratios, to be mapped. By inverting the spectral ratios under the constraint of the thickness of the sedimentary cover, known from previous gravimetric measurements, local S-wave velocity profiles have been retrieved. After interpolation between the individual profiles, the resulting high resolution 3D S-wave velocity model allows the entire area, as well as deeper parts of the basin, to be represented in great detail.

“…CM structure has been subjected to many devastating earthquakes. Table 1 includes some countries where CM buildings have been used for housing construction and the history of remarkable earthquake experienced by them [5][6][7][8][9][10][11][12][13][14][15][16][17]. As mentioned in the past literature, the overall performance of the CM building in these earthquakes was very satisfactory.…”

Sustainable housing using confined masonry buildings

Much of India is prone to substantial earthquakes, and vulnerability associated with both unreinforced masonry (URM) and improperly built reinforced concrete (RC) frame constructions has been unmasked by past earthquakes. URM structures present a severe hazard in earthquake-prone regions. And non-engineered RC structures can lead to devastating consequences. Housing for families in the economically weaker sector and the lower-income group is undoubtedly challenging to such events. Regardless of residing in a city or village, everyone desires a house with masonry walls and RC roof, just like the buildings in larger urban areas. Confined masonry (CM) construction, which is a popular building system in many countries, can fulfil this need of society. Though CM building started informally, the seismic performance is found to be really well in several destructive earthquakes. This type of construction combines the advantages of URM and RC structures and does not need sophistication required in RC construction. In this paper, the seismic response of URM, infilled RC frame and CM buildings is compared using past seismic performance and literature. It is concluded that confined masonry is a better alternative for sustainable housing in seismic-prone regions of India.

“…The authors have found it challenging to make a distinction between the damage grades 1 and 2 (DG1 and DG2) as defined by the EMS-98 scale. It is suggested to combine these two damage grades, in a manner similar to a Chilean damage classification (Moroni et al 2004).…”

Seismic Vulnerability Assessment of Low-Rise Reinforced Concrete Buildings Affected by the 2015 Gorkha, Nepal, Earthquake

et al. 2017

Low-rise reinforced concrete (RC) frames with brick masonry infill walls up to five stories high have been used for housing construction in Nepal since the late 1980s. Many buildings of this type were damaged and/or collapsed in the 25 April 2015 Gorkha earthquake (M 7.8), even in areas characterized with moderate shaking intensity such as Kathmandu Valley. Due to inadequate design and/or construction of RC frame components, these buildings essentially behave like masonry shear wall structures with a shear-dominant failure mechanism. The paper presents the findings of a field survey of 98 RC buildings affected by the 2015 earthquake. The main objective of the study was to correlate the observed damage in the buildings using the modified European macroseismic scale (EMS)-98 and the wall index (defined as the wall area in the direction of shaking divided by the total building plan area above the level of interest). The results can be used to help establish recommendations regarding the required wall index for low-rise RC buildings in Nepal.
