We present a micromanufacturing method for constructing microsystems, which we term ‘micro-masonry’ based on individual manipulation, influenced by strategies for deterministic materials assembly using advanced forms of transfer printing. Analogous to masonry in construction sites, micro-masonry consists of the preparation, manipulation, and binding of microscale units to assemble microcomponen...

Masonry buildings, when subjected to external temperature fluctuations, tend to regulate them either by storing heat in their thermal mass or by offering it back to the interior, with a time lag depending on the thermal capacity of the building and characterized mainly by the overall mass of the masonry. This time lag may vary from a few hours when lightweight masonry is concerned to several da...

Reinforced concrete (RC) with masonry infill is one of the most common structural typologies in Nepal, especially Kathmandu Valley. Masonry infills are typically made solid clay bricks produced locally Nepal. This study aims to calibrate spectral-based analytical method, namely, FAST, for Nepalese RC-infilled buildings. The FAST method has been initially conceived Southern European RC buildings...

This paper presents laboratory test results for two-column one-bay reinforced concrete (R/C) bare frames with or without masonry infills 1:3 scale prototypes when the top beam is subjected to horizontal cyclic loading using 50kN axial load per column. It well documented that affect dynamic characteristics of building structures. At same time, their uncertain behaviors have also been recorded. M...

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...

Non-linear static analyses are the most effective way to predict force-displacement curves of masonry structures, due to the complex non linear behaviour of masonry panels which makes inadequate any kind of linear static analyses. Nevertheless, the choice of the appropriate model to use is a matter of paramount importance, as many aspects must be taken into account in order to reach a good appr...

The main purpose of this paper is to give an overview on the state of the art of inspection, assessment and maintenance of masonry arch railway bridges by the presentation of the results of an ongoing international research project run by the International Union of Railways (UIC) with the participation of 14 railway administrations. The survey has shown that the European railways partaking in t...

Seismic assessment of masonry structures is plagued by both inherent randomness and model uncertainty. The former is referred to as aleatory uncertainty, the latter as epistemic uncertainty because it depends on the knowledge level. Pioneering studies on reinforced concrete buildings have revealed a significant influence of modeling parameters on seismic vulnerability. However, confidence in me...

This paper describes the prototype design, specimen design, experimental set-up, and experimental results of tests on three light-gauge steel plate shear wall (SPSW) concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity and emphasis is placed on minimizing their impact on the existing framing. Three singl...
