Software Features
1. Enhanced Basic Calculation Capabilities
- The “Basic Calculation” command now includes a live load reduction factor when reading SATWE/TAT load calculations. If a WDCNL.out file is present in the directory, the coefficient is extracted from it.
- Fixed an error where the design value was mistakenly used to calculate the base area when reading WDCNL.out or DCNL.out files.
- The “Bearing Platform Calculation” command has been updated similarly, adding live load reduction factors and fixing the same base area calculation error.
2. More Comprehensive Steel Structure Design
- Added European standard HE steel data to the hot-rolled H-beam database.
- Updated the bolt calculation module in the Steel Calculation Table to include additional steel plate thicknesses and support calculations for various bolt types.
3. Other Improvements
- Updated dialog box inputs for [asde_ct], [asde_stale], and [asde_stcale].
- Enhanced the “System Configuration” command to control whether the self-adjustment function for inserting or pasting block proportions is enabled.
- Added the “Insert Adjustment” command to enable or disable the self-adjustment feature within the current drawing.
- Introduced the “Convert Layer” command, which converts entities in the drawing from the naming conventions defined in
layerdefold.inito those inlayerdef.ini. - Modified the insertion section of the gallery module to automatically perform layer conversion.
- Updated commonly used standards, including:
- “Code for Design of Concrete Structures GB50010-2010”
- “Technical Specification for Concrete Structures of Tall Buildings JGJ 3-2010”
- “Mandatory Provisions of Engineering Construction Standards (Building Construction Part) 2009 Edition”
