Dynamic Behavior of a Historical Building

Given the particular difficulty in classifying and defining the characteristics of the structural systems of historical buildings, especially when they are part of complex historical constructions, the vulnerability study efforts becomes significantly more difficult than the study of regular modern structural systems. Furthermore, old buildings may have been altered repeatedly over time, may be founded on older buildings that got buried over and could be connected one to the others. This will cause dynamic interactions with other buildings or sub-structures during an earthquake. Therefore, the particular architectural and structural history of each structure adds uncertainties in the assessment of its seismic vulnerability. In this paper the dynamic response of CEDRAV building, part of the historical centre of Cerreto di Spoleto (Italy), is analyzed, by means of the data recorded by several temporary deployments of velocimeters. The complexity in assessing seismic behavior of the historical built environments is pointed out and so the dynamic interaction with adjacent buildings.

Research Type

The analysis of historical buildings Ngawen Temple has a purpose of knowing the history of Ngawen Temple and knowing the approach to the Ngawen Temple's geometry. This research type is descriptive research with a qualitative approach. The subject of this research is the historical building of Ngawen Temple. The data collection techniques used in this research are interviews and documentation (observation) directly. The interview was done with the temple officers around the building, and the documentation was taken directly. The data analysis technique is done by analyzing the buildings related to the geometry, such as the building's shape on the Ngawen Temple. The results of this study were obtained; namely, Ngawen Temple set in Buddhism. The Ngawen Temple complex consists of 5 (five) temples that line the parallel from north to south. Temple building facing the east. From the south of Ngawen Temple I, II, III, IV, and V, each temple plans the square. One of Ngawen Temple's uniqueness is the existence of 4 lion statues in every corner of temple II and Candi IV. Another uniqueness is the temple's architecture, found in a lion's statue that supports the four sides of the temple building reconstructed from the five buildings. The lion statue's carved style resembles the lion symbol of Singapore's country and serves the rainwater that comes out through the statue's mouth. The Ngawen Temple's shape resembles the cuboid's geometry, the rectangular pyramidal frustum, and the rectangular pyramid

Vulnerability Functions

The seismic behavior of structures composed by masonry blocks is analyzed using the discrete element method. Some features of the method are described including the representation of the block deformation, contacts and block interaction. The suitability of the method for the analysis of masonry structures is examined. The seismic behavior of some simple structural systems as well as that of some real structures is studied. It is shown that the method is able to reproduce important phenomena such as crack opening and joint sliding, which are responsible for the occurrence of structural damage and collapse. The collapse patterns of the analyzed structures are examined, reinforcing schemes using steel cables are considered and seismic vulnerability functions are obtained.

Nowadays, rising intensity of traffic is significant effect on entire world, because the endanger risk of adjacent buildings rises. Endanger risk is caused by traffic vibrations spreading through the bedrock, i.e. by traffic seismicity. Historical buildings are specific group of structures, which are especially sensitive on traffic seismicity effects. The aim of this article is experimental dynamic analysis of traffic seismicity effect on Traction substation historical building in Horný Smokovec, district Poprad in Slovakia. This structure is directly exposed to road and rail traffic effects. The experimental measurements of vibration levels were implemented, whose outputs had been vibration acceleration time records on this structure. In all experimental measurements, vibration levels and its transmission through the bedrock were detected, because of train crossing effecting on tower part of object (because the tower part is nearby the railway and it is also the highest place on building) and vehicle crossing. The study of dynamic interaction is implemented within the amplitude analysis. The spectral analysis and frequency transmission is presented in the paper within the frequency analysis. The evaluation of implemented traffic seismicity experimental dynamic analysis effecting on the traction substation object is the end part of analysis.

Each earthquake represents a particular moment in the history of the affected region. The seismicity in Italy reaches frequently high values, what makes it a country particularly affected by this kind of natural disasters. Historical constructions (in particular masonry ones) are structures that show a high vulnerability to the type of loads introduced in the sequence of a seismic event. This paper focus on the effects of the 6th of April 2009 earthquake, that affected the region of Abruzzo (Italy), over the historical buildings of the region, in particular churches, by establishing a set of different objectives directed to the understanding of their structural behavior and to the assessment of the extent of post seismic damage in this structures. During the emergency period that followed the earthquake, many churches and other historical constructions (towers, walls, palaces, etc…) were surveyed, according to the official 1st level damage survey forms for Cultural Heritage (C.H.), by the workgroup of the University of Padova (UNIPD). The information collected from these surveys was later inserted and organized in a database. A statistical work is presented, illustrating the referred information and focusing on the data related with the damage assessment of the considered monuments. This work presents an intuitive overview of the seismic effects over the surveyed churches, allowing not only to better understand the response of these structures to this particular action, but also correlating the earthquake data with its effects on the churches.
