- The 29th May 2012 Emilia Romagna Earthquake

- Earthquake engineering ; Seismic effects
- Keywords: Emilia Romagna Earthquake
- Description
- The 5.9Mw earthquake, which hit the Emilia-Romagna region of Italy on 20th May 2012 (see Rossetto et al, 2012) was followed on the 29th May 2012 by a 5.8Mw earthquake with epicentre 15km North West of the former event. This earthquake caused further damage to locations hit by the 20th May earthquake, and extended the affected area to the East-side of the province of Modena, resulting in 17 deaths and 14,000 homeless.
A team consisting of Dr Ioanna Ioannou, Randolph Borg and Jose Melo from EPICentre, and Viviana
Novelli from University of Bath, travelled to the affected areas on 2nd June 2012. The team spent
four days in the field, re-visiting Finale Emilia, San Felice sul Panaro, San Agostino and Mirabello as
well as visiting new areas such as Mirandola, Cento, Cavezzo and San Possidonio. Rapid surveys were
conducted that focused on the overall performance of residential, commercial, industrial and historical structures, emergency management and on geotechnical features of the two recent events.
The present report complements the first reconnaissance report (Rossetto et al, 2012) and should be read in addition to it in order to obtain a complete picture of the impact of the two moderate
events. Both reports can be downloaded from the EPICentre website (www.epicentreonline.com), where kml files with the georeferenced photos collected in the field for the two events can also be
downloaded (for viewing on Google Earth).

- Effects of Capacity Design Rules on Seismic Performance of Steel Moment Resisting Frames
- M.T. Naqash ; G. De Matteis ; A. De Luca
- Book Title / Journal: 15th World Conference on Earthquake Engineering
- Year: 2012 , Volume: , Series:
- Earthquake engineering
- Keywords: Seismic codes ; Moment resisting steel frames ; Seismic resistance ; Pushover analysis
- Description
- The current paper deals with the seismic design of 9-Storey office building using Eurocode 8 and AISC
(American Institute of Steel Construction) provisions, where the seismic load resisting system is composed of either spatial or perimeter moment resisting frames. According to EC8, Ductility Class High (DCH) and Ductility Class Medium (DCM) with behaviour factor of 6.5 and 4.0 respectively, are used. Whereas in the case of AISC code, only Special Moment resisting Frame (SMF) with response modification factor of 8 is employed.
In order to shed light on the pros and cons of the design criteria and thus the influence on the capacity design rules of the two aforementioned codes, designed frames are analysed by non-linear static analysis. The frame performances are measured in terms of overstrength and redundancy factors, strength demand to capacity and drift demand to capacity ratios, allowing interesting conclusions to be drawn.

- Enhancement of the seismic performance of AAC masonry by means of flat-truss bed-joint reinforcement

- Keywords: horizontally reinforced masonry ; cyclic tests ; displacement capacity
- Description
- Only few experimental tests are available in the literature on bed-joint reinforced load-bearing masonry. These are performed on prototypes with different masonry typologies, often reduced scale and, in any case, only for a small number of combinations of slenderness, axial load and boundary conditions. This work presents the results
of an experimental campaign including in-plane cyclic tests on autoclaved aerated concrete (AAC) masonry panels with thin bed- and head-joints filled with glue-mortar. Some of the specimens are made of unreinforced masonry, whilst in other the masonry walls are reinforced by means of bed-joint flat-truss reinforcement only. Based on the results of these tests, complemented by specific tests performed on wallettes realised with the two
different construction techniques, a possible strength criterion is proposed. The results indicate that the inclusion of bed-joint reinforcement has the double effect of improving masonry resistance and displacement capacity, hence reducing damage.
