Engineer's Studio(R) Ver.1.06.02
We introduce four points which are improved in this new version. When DLL file created by "Engineer's Studio() plugin SDK Ver.1.06.02", sold separately, is registered to OS, the "plugin-tab" button is displayed in the main screen (Figure1). For more detail, please refer to "Engineer's Studio(R) Plugin SDK Ver.1.06.02" on page 41. The number of levels for compression damage on plate elements has been changed from four to five. The compression level that has been added is the numerical value three times the peak strain of concrete. This value is compliant to the standard described in P173 of Standard Specification for Concrete Structures in 2007 [Design] - "It used to be that verification was approved if the vertical member does not give way to shear failure, but from now on verification will be approved if the main compressive strain of the surface of surface member does not reach the value three times the strain against compressive strength."(Figure2). The command "Square mesh element" used for creating plate elements is improved. This command can visualize the mesh being generated while moving the mouse, highlight new nodes when it is being shared with existing ones, and display the number of primitive to be generated (Figure3).It can load the strong motion seismograph data provided by "Kyoshin-Net(K-NET)" and the data obtained by strong motion observation provided by Japan Meteorological Agency.

We will introduce three points which are improved in this new version. The multi-thread process is improved to reduce the calculation time for large models with plate elements. For example, the measured result of "61,000 nodes + 14,000 spring elements + 21,000 plate elements + 6 steps of analysis" is displayed in Table 1.
The calculation time is the processing time of solver. It does not include pre/post processing time. The solver consists of two types of part: the part that can do simultaneous parallel processing by dividing the processing units, and the part that can only do uniprocessing. The vertical axis in the graph indicates the processing time for both processes. According to the figures, we can see that the calculation time is reduced in Ver.1.06.03. When the number of cores increase from one to two, from two to three, and from three to four, time is effectively reduced. But increasing further from four will not make much of a difference in time. If you want to use other software comfortably while calculating a large model, we can say that using a high-performance computer with from eight to twelve cores (logical core) is the most cost-effective way. The horizontal axis in the graph indicates the uniprocessing time of solver. We will improve the processing speed further by also looking into this part. "BMR(CD) damper" was added to the non-linear property of spring elements. This is one type of bridge beam's appendage, which is the compression damping system with back up function, and sold by OILES Corporation. It provides the damping effect of repetitive earthquake(Figure4). Moreover, a tool which allows "loading, calculation, saving of the result" of the multiple data files(*es) in order has been added. The es files in the folder can be automatically processed by specifying the folder.
