Historical Buildings in the Ostrava and Karviná Region and their Seismic Loads
نویسنده
چکیده
This paper refers to the present state of historical buildings situated in the Karviná and Ostrava region and also to the problems of these buildings caused first of all by surface vibrations generated by mining-induced seismicity in the Karviná region and by technical seismicity caused by industrial activities and transportation in the Ostrava region. Designing of earthquake-resistant structures and analyses of structures affected by surface vibrations are governed by standards ČSN 73 0036 Seismic loads of buildings, ČSN EN 1998–1 Design of structures for earthquake resistance and ČSN 73 0040 Loads of technical structures by technical seismicity. In the second part of this paper, these three standards are described and compared. In the last part of the paper, the measured data from the last six years are shown and reviewed, specifically the maximum values of amplitudes of oscillation velocities. These data come from seismic monitoring using solitary stations of the Institute of Geonics, situated in surface structures in the Karviná region, and from experimental measurements of the influence of transport in Ostrava in 2004.

متن کاملSeismic Consolidation of Rural Adobe Building (Case Study: Tabas Isfahak Historical Village)
After the earthquake of Tabas at 19:36 pm in September 16, 1978, a large part of the buildings were destroyed and there were many human casualties. With more research, it can be seen that a significant number of these damages and losses from the earthquake had been related to rural buildings around the city (Tabas). Due to the fact that the Tabas area has a warm, dry and desert climate, Village...
متن کاملExperiments on Coupled Technique for Adjacent Similar Buildings
Increasing the population, urbanization has led to the rapid construction of buildings. Due to space constraints and an increase in land cost, these buildings are built too close to each other and can cause damage under dynamic actions such as earthquakes. A new technique, known as Structural coupling, has been developed recently, has found very effective in dissipating the dispersive vibration...
متن کاملEvaluating Response Modification Factors of Concentrically Braced and Special Moment Steel Frames in Duplex Buildings
Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...
