Seismic reinforcement applications

One of the main purposes was to prove applicability of LBB conception. Destructive testing of metal samples was done. Also stress and fatigue analyses were performed, considering the actual data for seismic impact in the KNPP site. These analyses show the expediency of additional seismic reinforcement of equipment and piping, and reinforcement was executed later on. [Pg.24]

Application of HPFRCC in structures that should be earthquake-resistant is a relatively new but already confirmed option. It has been proved that ductile behaviour, increased resistance and damage tolerance can be achieved, thus reducing necessity of a special anti-seismic reinforcement by traditional bars or prestressing. [Pg.358]

The most challenging of these applications has been the location and characterisation of anomalies in thick concrete structures using seismic methods and the detection of reinforcing steel and pre-stressing cables in congested structures using radar. [Pg.999]

Fig. 6b illustrates the type of simple interpretation of the fault structure often used as a basis of fault seal analysis. This interpretation is based on representation of the fault as a single fault plane, where the offset is assumed to be equal to the seismic (cumulative) offset. This is clearly not valid as a representation of throw distributions for use in fault seal analysis. Fig. 6 also illustrates that sub-seismic fault populations can be clustered around larger faults with extensive areas of low fault densities away from the large faults. This has important implications for the spatial distribution of sub-seismic faults and emphasises that uniform distributions of small faults are not always applicable (except perhaps in areas where more uniform straining is associated with doming). The information contained in Fig. 6 reinforces the results of other recent studies which have noted different fault... [Pg.25]

A large amount of carpet waste is disposed of in landfills each year. This not only poses economical and environmental problems to the industry, it also represents a severe waste of resources because the waste material can prove to be valuable for construction applications. This study focused on the use of carpet waste fibers in fiber reinforced concrete and demonstrated that such reinforcement can effectively improve the shatter resistance, toughness, and ductility of concrete. Performance enhancement has also been observed in the drying shrinkage test. Such improvements in concrete performance is especially beneficial for concrete structures in seismic zones as the increased toughness could improve the reliability and shock resistance of the structures. [Pg.226]

In this paper, the current seismic retrofitting systems for reinforced concrete piers/columns and bridge-falling prevention systems at the abutments and piers in Japan were studied. The application of epoxy resin for both systems was investigated and discussed. Furthermore, seismic design and construction for newly built structures were also introduced. [Pg.208]

In this study, the performance of the Mesh Reinforced Mortar (MRM) application, which is one of the proposed methods for strengthening of RC structures in the Turkish Seismic Code (2007), was verified using pseudo-dynamic (PsD) tests. In this context, a three-bay, three-story frame in Vi scale was prepared and tested. The earthquake load was applied at each story level by means of servo-controlled actuators. The grotmd motions were synthetically derived from the Diizce city center site specific acceleration spectra. The hollow clay tile (HTC) masonry wall in the mid bay was enhanced with MRM. [Pg.185]

Application of (carbon fibre) polymer composite blankets as vibration damping stabilisers for bridge columns, seismic retrofits and structural reinforcements are recognised in recent years, while rubber seismic bearings have been used for a long time. [Pg.8]

Over last several years, scientific interest towards innovative fiber-reinforced polymer (FRP) applications for structural reinforcement on one side and the peculiarity of the extremely diversified Italian architectural heritage on the other directed the attention of many researchers to the fields of structural mechanics, constructions, structural reinforcement, and seismic engineering. Several scientific programs have resulted from this, funded by the most important Italian research centers, in particular, by MIUR and CNR. [Pg.55]

The seismic efficiency of the planned intervention can be evaluated by the increase of failure of horizontal shifting deriving from the application of the reinforcement. [Pg.96]

In this paper, a simplified approach for probabilistic seismic performance assessment is snmmarized and applied to the example of a four storey reinforced concrete (RC) frame with and withont masonry infills. For the determination of an IN2 curve for an infilled frame, the extended N2 method, which is applicable to infilled RC frames, is employed (Dolsek Fajfar 2004b, 2005). [Pg.242]
