Hygrothermal Monitoring of Replacement Infill Panels for Historic Timber-Frame Buildings: Initial Findings

The aim of the article is to present results of seismic analysis results of two real-sized timber frame buildings subjected to seismic excitations. The first model was insulated with mineral wool, the second one with polyurethane foam. Technology and specifications involved in both models construction is based on the previously conducted experimental research on timber frame houses, including wall panels tests, wall numerical models and study on material properties and precisely reflect results of the those research. During the seismic analysis reference node located in buildings were selected. In selected node displacement values were measured and compared between two analyzed models. The results of the numerical analysis presented in the article indicate that the application of polyurethane foam for a skeleton filling of the timber-frame building leads to the increase in stiffness as well as damping of the whole structure, which results in a considerable increase in the seismic resistance of the structure.

Reinforced Concrete Frame Structure

In North-south earthquake belt, half of more than Ms 8.0 great earthquakes were centralized since the history records were existed in our country. In order to study the typical buildings in this seismic belt, the seismic damages of the typical buildings occurred during 22 earthquakes in North-south earthquake belt, whose earthquake magnitude were more than Ms 6.0, were organized and analyzed. The seismic damage and its matrix of kinds of buildings belonging to the North-south earthquake belt in different intensities were obtained. The statistic results were obtained by comparison and analysis. According to the results of analysis, the seismic capacity of kinds of typical buildings in this region was provided: reinforced concrete frame structure showed fine seismic capability in all previous earthquake whose seismic damage was the slightest in the real statistics results; secondly were those of masonry and mortised timber frame buildings; the seismic damage of buildings, which was combined with timber frame and soil, stone, brick walls was the most serious.

Purpose The energy retrofit of the existing building stock, and specifically the thermal upgrading of the buildings’ envelopes, has been identified as a key action for both the decarbonisation of the built environment and the reduction in fuel poverty. When considering the energy retrofit of heritage buildings it is, however, important to recognise both the technical issues that this entails and the potential impact on their cultural value and the emotional responses to it. The purpose of this paper is to focus on the thermal upgrading of historic timber-framed buildings in the UK. Design/methodology/approach The paper begins by exploring the cultural significance of this form of building construction, before examining three case studies using both quantitative and qualitative methodologies. Findings The results show that whilst the application of energy retrofit actions to this emblematic typology may have limited success, the emotional connection of the buildings’ occupants often results in the work resulting in higher user satisfaction than would otherwise be expected. Research limitations/implications Although limited in number, the three case studies provide an insight into the complex issues surrounding the low energy retrofit of historic timber-framed buildings. Further research into this area is encouraged. Practical implications The paper contains the monitoring of specific retrofit details, the results of which should inform future projects. Social implications The review of the cultural significance of historic timber-frame buildings in the UK underlines the importance of the conservation and continuing survival of these buildings. Originality/value Previous heritage retrofit research in the UK has focussed on solid wall construction with little investigation into the issues surrounding the retrofit of historic timber-frame buildings. This paper explores this previously under-researched area. Additionally, this paper begins to explore the possible links between occupants’ emotional connection to historic buildings and their perceived levels of comfort.
