Finite element prediction system for welding and solidifying crack in virtual environment

The invention provides a finite element prediction system for welding and solidifying a crack in virtual environment, which relates to the technical field of finite element prediction software for welding and solidifying a crack, and the complex simulation and the prediction processes of welding and solidifying a crack are simplified into the simple operation and settings of an interface. A preliminary processing subsystem comprises an interface operating module, an MSC.Marc interface document module, a subprogram.f file module and an invocation MSC.Marc software executing and computing module, and a post processing subsystem comprises a MSC.Marc software computed result processing module, a MatrixVB function module, a Matlab software module and a graphic display module; a solidified crack predicting subsystem comprises a resistivity curve loading module, a judgment module and a result output module. The application of the invention enables a common welding engineering technician to carry out the numerical simulation and prediction for welding and solidifying a crack; the computed result is processed, and the storage space of a result file is decreased; the result file is converted into a file format convenient for graphic display, and the computed results of a temperature field and a stress strain field are visually displayed in a graphic form.

Grouting connection construction method

The invention discloses a grouting connection construction method which is used for connecting vertical reinforcements of an assembled concrete structure. The grouting connection construction method includes the steps: firstly, embedding a plurality of grouting connection devices at one end of a precast concrete unit to be connected in advance; secondly, lifting the precast concrete unit and then manufacturing a grouting box dam; thirdly, grouting horizontal gaps and then grouting the grouting connection devices. The grouting connection devices are connected with connection reinforcements extending out of a lower unit. Plugging grouting of the horizontal gaps and grouting of the grouting connection devices can be performed within the same day, so that the mounting efficiency of the precast concrete unit is greatly improved, the grouting connection construction method can be implemented in a subzero temperature environment even in winter, construction difficulty is reduced, and working efficiency is improved.
