This work presents an analysis of different proposals of rehabilitation of a masonry building, built around the beginning of the XX century for public schools, in the highest seismic risk zone of Argentine; and which was closed down after Mendoza`s Earthquake in 1985. The building has masonry walls of artisanal ceramic bricks and wood-framed roof but it does not have lateral ties. Currently, it...

In this paper a Romanesque masonry church is analysed in order to assess its structural behaviour and its seismic vulnerability with respect to the actual state of conservation. Starting from a specific case study, a contribution to the issue of modelling and analysis of monumental masonry buildings under seismic action is provided. A finite element methodology for the static and dynamic nonlin...

Abstract: This paper introduces a new numerical method for the analysis of infilled steel frames with hollow clay blocks. This approach is based on the brittle cracking model of ABAQUS. The results of the in-plane calibration analyses obtained with four experimental tests are presented and discussed. The first test was a bare steel frame used as a control specimen. The second was similar to ...

The assessment of the seismic vulnerability of all school buildings located at Chorrillos and Barranco districts in Lima, the capital city of Peru, was conducted using the Rapid Visual Screening procedure of ATC-21. A total of 28 school buildings were evaluated in Barranco, and 80 in Chorrillos, comprising all kindergarten, primary, and secondary school buildings existing in these two districts...

Abstract To explore the optimization seismic design of frame-multi-ribbed composite wall structure, firstly finite element model a six story structure is established based on software SAP2000. Secondly critical parameters multi under action are analysised using analysis software. Finally response different rib combinations and optimal arrangement rule studied. The results reveals that lateral s...

Abstract—Past earthquakes have shown that seismic events may incur large economic losses in buildings. FEMA P-58 provides engineers a practical tool for the performance seismic assessment of buildings. In this study, FEMA P-58 is applied to two typical Italian pre-1970 reinforced concrete frame buildings, characterized by plain rebars as steel reinforcement and masonry infills and partitions. G...

Traditional Chinese wood residences consist of timber frames with masonry infill walls or other types infill, representing valuable heritage. A field investigation traditional village dwellings in northern China consisting mud and stone was conducted. Their construction characteristics are reported, static cyclic tests were performed on two full-size wood-stone hybrid different configurations (...

Reinforced concrete frame buildings with Open Ground Story (OGS) are one of the most common building configurations in urban habitat. These configurations are known to be vulnerable to seismic excitations, primarily due to the sudden loss in strength in the ground story and differential stiffness distribution throughout the structure. The differential stiffness distribution is attributed primar...

This paper is in two parts; firstly a method of numerical modelling is described that is being used to investigate the performance of masonry strengthening; secondly how more pragmatic approaches are being used for localised masonry repairs with examples taken from the Mosque of al Ghuri, Cairo. Numerical modelling based on a discrete element formulation has been employed to simulate the respon...

Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...
