MacOS & PC version 5.8

Version 5.8 has been release for Apple MacOS and Microsoft Windows.

The user control of the automatic trial and adjustment computations has been improved.

There is a check box to show the progress dialog. When this is not checked there is no progress dialog and the computations are faster.

There is an editable number that controls the speed when the progress dialog is showing.

The Stop, Step, Go and Escape buttons work on both the platforms.

Minor changes have been made to the User Guide that give details of these new facilities

MacOS version 5.7 released

The MacOS version 5.7 has been released. The main difference between this and the previous version is that it is compatible with Apple’s new technology.

Also released is the Mac & PC version of the “Composite floor” example. This illustrates the facilities for prestressing, staged-composite construction, creep and concrete shrinkage. Detailed Step by step instructions are included.

Now the xsf files for this example are exactly the same for all platforms. However the problem still exists with the xsf file included with iPhone version 5.7 (see October 31, 2018 blog post).

Android phone platform

The application for an Android phone has been released and is on the Google Play store under the name “Cross-section analysis of reinforced concrete”.

The operation of this Android phone application is similar to the operation of the Apple iPhone application.

Eventually a full user guide that serves both the Android phone and the iPhone will be available. This will be an adaptations of the existing iPhone user guide. In the meantime a user guide specific to the Android phone will be available although this will cover only what is different.

Dimmed “>” button is enabled

There is a bug in iPhone xsec in that the “>” button in the top right corner sometimes appears dimmed as though it is disabled when in fact it is enabled. This is caused by a bug in the software used to create xsec rather than in xsec.

When this button is disabled it is made not visible so that whenever it is visible it is enabled; dimmed or not.

This does not affect Mac xsec or PC xsec.

Problem with “Composite floor” example

There is a problem with the ~STAGE1.XSF file that is part of the “Composite floor” example included with iPhone xsec version 5.7.

If the stage 2 computations follow on from stage 1 this file is not used. It is intended to allow the computations to start at stage 2.

This file is not compatible with the step by step instructions. (It is compatible with the Mac & PC version of the instructions although they have not been released yet.) It has the material of “Rib” set as “Air” where as it should be “Rib concrete”.

To correct this add the following to the iPhone instructions step 2-2:

a             Tap the “C” at the bottom of the display to change the display to the Components list.

b             In that list tap “Rib” to open the component editor for “Rib”.

c             The editor display includes a label “Material=” and “Air” in an adjacent selection box. Tap on “Air” and a list of materials should appear.

d             In that list select “Rib concrete” and tap “Done”.

e             Tap the “<” back button in the top left corner to return to the components list.

iPhone version 5.7

iPhone version 5.7 has been released along with a work example of a chronological sequence that illustrates the facilities for prestressing, staged-composite construction and creep and shrinkage in concrete. Detailed Step by step instructions for an iPhone with this example are also released.
This iPhone version 5.7 includes some improvements to the file and entity name facilities. There are consequential minor changes to the iPhone User Guide.
No new version for Microsoft Windows or Apple MacOS have been released at this time. A version 5.7 and step by step instructions for the example for these platforms are to be released soon.

iPhone version 5.6

iPhone version 5.6 has been released. Version 5.5 was released in December 2017. Both these releases fix various bugs that had become evident. All these bugs were in the user interface and did not affect the computation results.

None of these bugs affected the Microsoft Windows version nor the Apple MacOS version. No version 5.5 nor 5.6 has been released for these platforms. Nevertheless, the next release for these platforms will be named 5.6 or later to keep the version numbers consistent between the various platforms.

Version 5.4 and iPhone platform

Version 5.4 and also an Apple iPhone version have been released. The Apple iPhone version is available on the Apple App Store. (Search on ‘xsec’ to find it.)

A number of minor problems with the previous version have been fixed including:

  • The problem with the ‘Save’ item on the ‘Files’ menu in the Windows version.
  • The problem of the focused dialog being obscured by other dialogs in the MacOS version.

Also a generic cross-section example that illustrates the various measurement unit systems appears when the ‘Choose’ button on the ‘Choose a unit system’ dialog is pressed. This is so the new user is not faced with empty list boxes on the main dialog.

A problem with the Files – Save menu item

An annoying bug in the Microsoft Windows version of the application has been pointed out. The ‘Save’ item on the ‘Files’ menu can cause the last previously opened XSF file to be overwritten. This happens with a new cross-section description when that ‘Save’ item is used before the ‘Save as’ item. The new description overwrites the description in that previous XSF file. To avoid this problem use the ‘Save as’ item at least once when starting with a new cross-section description.

In the next version release of the application that ‘Save’ menu item will be disabled on a new cross-section description until ‘Save as’ has been used.

This problem does not affect the Apple OS-X version of the application.
