This paper compiles the indigenous technologies adopted in the Bhaktapur municipality, Nepal in the unreinforced masonry construction of traditional Newari houses constituting more than 90% buildings in Bhaktapur municipality and their significance during the earthquake. The building units adopted in this area are studied with respect to their performance during earthquake on the basis of seismic resistant design philosophy. The traditionally built non-engineered buildings have drawn the attention of disaster managers for many years; in this regard, the unreinforced masonry buildings (Newari houses) were assessed after the Sikkim-Nepal boarder earthquake of 2011.Still, the buildings constructed before the starting of engineering construction in Nepal are widely used for residential purpose at this culturally rich city and the traditional building construction technology which is the indigenous technology has been practiced for centuries too. The building features are analyzed with respect to their seismic performance and their contribution was analyzed as per the historical database; established practices and theories for earthquake resistant design (EQRD). The collected features and the analyses proved the features of the buildings to be sound during earthquake, though; the buildings were constructed with indigenous technology which nevertheless consults the EQRD within it. The indigenous technology at this city has been attached with the culture of the Newars for centuries.

The results of lateral resistance tests of masonry walls and shaking table tests of a number of models of masonry buildings of various structural configurations, built with various materials in different construction systems, have been analyzed to find a correlation between the occurrence of different grades of damage to structural elements, characteristic limit states, and lateral displacement capacity. On the basis of correlation between acceptable level of damage and displacement capacity, it has been shown that the range of elastic force reduction factor values used to determine the design seismic loads for different masonry construction systems proposed by the recently adopted European standard Eurocode 8 EN-1998-1 for earthquake resistant design are adequate. By using the recommended design values, satisfactory performance of the masonry buildings that have been analyzed may be expected when subjected to design intensity earthquakes with respect to both the no-collapse and damage-limitation requirements.

Progress does not amount to destroying the future, but to preserving its essence, to generate the impetus to do it better today (Y. Ortega Y Gasset 1951). Working in the areas of history and construction technology, the spirit of these statement guided my research: developing a research method for buildings not listed (yet) as monuments but needed to be analysed before the next approach. When studying buildings it is essential to consider not only the art history, social and urban planning factors, but especially the construction engineering aspects. In this way, a deeper understanding of the underlying design and building methods used in our built environment can be developed. There have been many historical and architectural studies of buildings. The period since the Second World War has received particular interest. Unfortunately, most of these studies do not address the technical aspects of the construction of these buildings. However, these issues were covered by publications at the time these buildings were constructed. Technology provided me with the inspiration to develop a more comprehensive research method to assess buildings: Analysing Buildings from Context to Detail in time: ABCD research method. Technology, at academic level, should be considered in the analysis of a building. Here we are concerned with construction engineering, the study of the requirements associated with constructing buildings. The Analysing Building Construction in time research matrix (ABC matrix) can be used in practice. It incorporates the study outcomes which relate to the building itself. Contextual aspects as well as building aspects are included. They can be analysed at the three time levels to draw conclusions which are relevant to the future existence of the building. The case study of the Friesland Provincial Library in Leeuwarden will be worked out in the conference paper.

Abstract. The purpose of this study is to scrutinize and interpret the damages to masonry buildings after a series of earthquakes that occurred in Van, which is an eastern city of Turkey, within 17 days in 2011, i.e., the first earthquake hit on 23 October having the magnitude 7.1, and the second on 9 November with the magnitude 5.6 on the Richter scale. These consecutive earthquakes and their aftershocks caused extensive damage and the collapse of buildings in the city of Van and its villages and especially its near town, namely Ercis. For the investigation of masonry buildings, Hacibekir district, which is one of the regions comprising the highest density of masonry buildings in the city of Van, was selected and the seismic performance of these buildings was observed, tested in the field, and interpreted according to the Turkish earthquake-resistant design codes. In this region, masonry buildings were classified as adobe, unreinforced and confined masonry buildings. As a result of this field study, it was observed that whereas the confined masonry buildings had usually shown good performance during the earthquakes, the adobe and the unreinforced masonry buildings were seriously damaged and some of them were partially collapsed.

The brick-timber structures have a long history and are still used widely in Chinese rural area at present. A large amount of structures were damaged in Wenchuan earthquake occurred on May 12, 2008, and the brick-timber structures in different intensity regions were investigated in detail. Based on the investigate data of Wenchuan earthquake and other previous seismic data, the typical damage of brick-timber structures are summarized and the earthquake resistant design methods and research status are discussed, the earthquake resistant capability of brick-timber structure are also analyzed. Combined with current country codes, the constructional measures for earthquake resistance and construction technology of brick-timber structures are studied. Finally, some reasonable suggestions on the seismic strengthening and reconstruction of this kind of structure after disaster have been given.

The seismic performance of the few masonry structures present in the Kobe area and subjected to the severe Hyogo-ken Nanbu earthquake is a minor concern when compared to the overwhelming damage suffered by other types of structures. However, in order to dispel the myth that masonry structures are nonexistent in Japan as well as a few other misconceptions, and for the sake of completeness within the concerted multipaper reporting effort on the Hyogo-ken Nanbu (Kobe) earthquake by the Canadian reconnaissance team which visited the epicentral area of this earthquake, a brief description of the past and present state of masonry construction in Japan is first presented, followed by a short description of the damage to unreinforced masonry buildings, masonry garden-walls, and nonstructural masonry elements, as observed by the authors during their visits to the Kobe area. Key words: earthquake, seismic, masonry, buildings, bearing walls, unreinforced masonry, reinforced masonry, failures, design codes.

High Energy Consumption

The acceleration of the development of economy and the construction of urbanization has promoted the development of the construction industry, and the construction technology of various construction projects has been continuously innovated. In the past, the building construction often suffered from disadvantages such as high energy consumption and generating large amounts of garbage. Modern construction techniques are actively improving these problems. Prefabricated construction techniques are widely used in the building construction, such as electrical pipeline construction, which makes electrical engineering construction more convenient and environmentally friendly. This paper mainly discusses the construction application of prefabricated electricity in the construction from the aspects of pipeline embedment, lightning protection grounding, the position of electric boxes and so on.
