ABSTRACT:The design of structures subjected to natural hazards such as earthquakes and typhoons demands safety of structures which is governed by the natural frequencies and the amount of damping in each mode of vibration. Fundamental frequency of a building and its damping have a remarkable effect on the magnitude of its response. The ability to predict these characteristics at the design stag...

Nowadays, many buildings with steel Moment Resisting Frames (MRF) are built in seismic zones when seismic codes are at its early stages of development, and as such, these structures are often designed solely to resist lateral wind loads without providing an overall ductile mechanism. On the other hand, current seismic design criteria based on hierarchy of resistance allow enhancing the structur...

Finnish national research project, Userand Businessoriented Suburb Renovation Concept (KLIKK), was started in January 2012 and will end in June 2014. The perspective of energy efficiency is emphasised in the project, but also it addresses what improving the energy efficiency of suburban apartment buildings means from the standpoint of architecturally valuable buildings representing different pe...

By location of a building in the vicinity of underground tube structure the effect of train operation excites the groundborne vibration. The solution of vibration transfer from the subsoil environment to the building structure is demonstrated using the example of a multistorey reinforced concrete building. The application of an elastic layer at foundation base level is used in order to eliminat...

the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

Residential energy consumption has been increasing significantly in Danang, Vietnam, recent years due to improvement living standards. In order plan housing conservation measures, it is necessary clarify information, people's lifestyles, style and usage of equipment. The purpose this study the characteristics for further simulation analysis next step. For purpose, a questionnaire survey 300 hou...

The floods in 2002 and 2013, as well the recent flood of 2021, caused billions Euros worth property damage Germany. aim project Innovative Vulnerability Risk Assessment Urban Areas against Flood Events (INNOVARU) involved development a practicable model that enables realistic statements for residential building stock. In addition to determination local risks, it also takes into account vulnerab...

In the framework of the European SCenarios for tsunami Hazard-induced Emergencies MAnagement (SCHEMA) project (www.schemaproject.org), we empirically developed new tsunami damage functions to be used for quantifying the potential tsunami damage to buildings along European-Mediterranean coasts. Since no sufficient post-tsunami observations exist in the Mediterranean areas, we based our work on d...

Underground structures at shallow depths are often constructed for metro lines, either in loose or dense layered soils. Tunnelling in urban areas is predominantly under surface structures and on tunnelling, innumerable changes in the form of distortion take place in strata surrounding the tunnel. Extent of displacement/damage to buildings or the tunnel-soil structure interaction depends on the ...
