retrofit
We also proposed a new gantry design to make the whole system compact to retrofit existing linac vaults.
      
Complex retrofit TGMP-314Ts boilers TETs-23 of OAO Mosenergo reducing emissions harmful substances atmosphere
      
System study for a tens MWe size coal-fired MHD retrofit pilot power plant in China
      
Fibre-reinforced polymer (FRP) composites were widely utilized in civil engineering structures as the retrofit of reinforced concrete (RC) columns.
      
The Concrete Committee of the Japan Society of Civil Engineers (JSCE) has set up a technical committee on the retrofit of concrete structures by continuous fiber-reinforced polymer sheet (CFRP sheet).
      
The objective of this paper is to present the results of a demonstration project to apply externally bonded CFRP fabrics to retrofit a simple span prestressed concrete girder with improved repair and hardening techniques.
      
Fibre-reinforced plastic (FRP) materials have been recognised as new innovative materials for concrete rehabilitation and retrofit.
      
Retrofit of CD-6 (smith) impeller in fermentation vessels
      
The research establishes a basis for testing our understanding of these processes in the case of hospital retrofit decisions.
      
In this respect, this study represents results of fragility curve development for two (2) sample bridges typical in southern California, strengthened for seismic retrofit by means of steel jacketing of bridge columns.
      
Monte Carlo simulation is performed to study nonlinear dynamic responses of the bridges before and after column retrofit.
      
The improvement in the fragility with steel jacketing is quantified by comparing fragility curves of the bridge before and after column retrofit.
      
In this first attempt to formulate the problem of fragility enhancement, the quantification is made by comparing the median values of the fragility curves before and after the retrofit.
      
Effect of seismic retrofit of bridges on transportation networks
      
As an example, the system performance degradation measured in terms of an index, "Drivers Delay," is calculated for the Los Angeles area transportation system, and losses due to Drivers Delay with and without retrofit were estimated.
      
However, buildings with retrofit alternatives exhibited lower damage levels changing from no damage to irreparable damage states.
      
The developed fragility curves can be used for the economic losses due to earthquakes, and the seismic vulnerability of the bridges estimated from the curves provides the priority of retrofit.
      
Therefore, it is necessary to assess the vulnerability of the bridges and retrofit measures are required to increase the seismic resistance of the bridges.
      
Fragility curves are needed for assessing the vulnerability of bridges to unscheduled events and for setting retrofit and/or repair priorities.
      
Therefore, it has practical significance for the seismic zoning, the design and retrofit of the aseismic structures on the soft soil in China.
