8.4 New Features

Category	Description
User interface	Significant overhaul of user interface introducing: Customizable toolbars Interactive status bar Improved dockable panes
General	Support has been added for new or revised design codes ACI 318-14 & ACI 318M-14 CSA A23.3 CSA S6 IRC 112 IRS Bridge EN1992 (country specific variants)
User interface	The Gateway has been revised to provide access to all the data in a single pane.
User interface	There are minor improvements to the interaction with graphic views. This allows some editing directly from the graphics. Graphics can now be saved in svg format in addition to the existing file formats. Better dimensioning information is provided for standard section shapes.
User interface	The handling of material models in AdSec has been rationalized allowing more flexiblity in the use of material models and more models being available over a greater number of codes (e.g. Mander curves). Additionally direct reference to standard material curves has been removed and all materials are now ‘user materials’ which can be initialized to ‘standard properties’. The defined material curves can be exported as csv files.
Output view	Text output has been revised to be clearer and to give the user greater control. The most significant change is that stress/strain results can now be calculated and reported at user specified intervals along the perimeter of sections.
API	AdSec can now be run from a command file which allows functionality such as opening and closing files, analysis and output of results in text or graphical form.

NCR-11462	Analysis	The k2 parameter for crack with calculation was derived from the interpolated strain plane rather than the cracked strain plane.	Build 37
NCR-11451	Analysis	SLS calculations to IRC112 do not produce crack width output.	Build 37
NCR-11440	General	The k3 parameter for crack width calculations are incorrect for French and Danish versions of Eurocode. In the French case the equation is incorrect and in the Danish version the default Eurocode value is used rather than the value in the National Annexe.	Build 37
NCR-11427	Analysis	Intermediate analysis (BS5400/HKSDM) does not allow for a creep value, so gives results the same as a short-term analysis.	Build 36
NCR-11427	File I/O	When saving data as a text file, the reinforcement material can be lost when the code does not involve a material (γ/φ) factor.	Build 36
NCR-11396	File I/O	In slab models where bars are defined by a pitch there is a correction for a non-integer number of bars. When this model is saved to file and re-opened the correction factor is lost leading to an underestimate of the slab strength.	Build 35
NCR-11394	General	The scaling of graphical printed output is worng by a factor of 1000.	Build 35
NCR-11392	File I/O	Reading AdSec text files with explicit material curves the curve definition is lost. This does not affect binary files.	Build 35

NCR-11347	File I/O	AdSec can crash when a chart analysis is selected and the section refers to an undefined material.	Build 33
NCR-11346	Analysis	When using CSA A23.3 for N/M charts the compressive axial limit is interpreted wrongly (by using the section dimension in m rather than mm) leading to axial load factors that are too small.	Build 33
NCR-11317	Analysis	When using DIN EN 1992 the crack width calculation does not set k1×k2 = 1 as per the German National Annexe leading to incorrect crack widths.	Build 33
NCR-11309	Analysis	There is an issue with the crack width calculation for the CSA S6 code with prestressed bars. With prestressed bars where the applied loads exclude the prestress anchorage the prestress was included in the checks for bars in tension. This prestress is now excluded from the calculation of most tensile bars.	Build 33
NCR-11294	Analysis	The value of ζ is now set to 0 if the section if uncracked, irrespective of the value of β.	Build 33
NCR-11285	File I/O	Dxf export of the section is now working.	Build 32
NCR-11280	Analysis	The crack width calculation to CSA S6 has been modified so that As is based on the factored bar area (for slabs) and the db is based on the largest bar in the tension zone.	Build 32
NCR-11279	Analysis	The welcome screen cannot be disabled.	Build 32
NCR-11251	General	There can be a problem with large link diameters in slab sections and template reinforcement given a message "links too large for section". This can be avoided using general reinforcement.	Build 32
NCR-11229	General	In Moment/curvature (M/κ) charts the specified maximum moment is ignored and instead the capacity is used as the upper limit for the calculation.	Build 32
NCR-11176	General	EC3 steel design grade S450 (EN) name is shown incorrectly as S460 (EN).	Build 30
NCR-11171	General	When the section is a slab with template reinforcement there is an area factor associated with the bars to give the correct area across the slab. When the section is resized this is lost leading to incorrect bar areas in the calculation. Opening the reinforcement wizard resets this, so avoiding the program.	Build 30
NCR-11137	Output view	AdSec will crash if materials are being output in a grid view.	Build 30
NCR-11137	Output view	When outputing elastic section properties for ‘all’ sections the properties reported ‘including reinforcement’ are always those for the current section.	Build 30
NCR-11119	Analysis	When using the Hong Kong Code of Practice 2013 the 0.67 factor on the concrete strength is set to 1 giving an overestimate of the strength.	Build 29
NCR-11113	Analysis	Changing design code to one using an FIB material would cause a strange stress-strain curve to be generated due to the dafault value for Em/Esecant not being updated.	Build 29
NCR-11108	Analysis	Crack widths for EN1992 with UK national annexe did not allow for calculation of crack width for durability.	Build 29
NCR-11104	General	Documentation for text file i/o not correct for rebar.	Build 29
NCR-11103	Analysis	SLS analysis to IRC112 can cause AdSec to crash.	Build 29
NCR-11092	File I/O	When using IRC 112 there are problems reading files. A message is dislpayed warning that the code is undefined. This does not affect other design codes.	Build 28
NCR-11088	Analysis	If a section references an undefined material AdSec will crash when doing an analysis.	Build 28
NCR-11085	Analysis	The calculation of the area of rebar for the CSA S6 crack width calcuations was using the total area of rebar in the tension zone rather than the area in the effective tension area.	Build 28
NCR-11084	Analysis	The setting of the prestress include/exclude option for multiple pre-stress bars results in the opposite option being set.	Build 28
NCR-11092	General	When using ACI 318M the value of the design strength of the concrete is being returned as f′c rather than 0.85 × f′c.	Build 26
NCR-11071	General	User defined tendon materals are not available in the general reinforcement dialog.	Build 26
NCR-11065	General	The option of explicit material curves for concrete and rebar are missing for the CSA S6 design code.	Build 24
NCR-11051	General	EN 1992 and ACI 318 allow extra parameters to be specified as part of the rebar properties. These were being overwritten and lost.	Build 24
NCR-11049	General	When specifying steel materials the stress-strain curves may not be generated correctly, leading to incorrect stress-strain relationships being used in the analysis. For Eurocode this also includes a non-standard γm value for the steel.	Build 24
NCR-11046	General	There are a couple of issues with rebar properties dialog: The hardening parameter is available for material models which don't require this. The failure strain cannot be entered (although the value can be copied).	Build 24
NCR-11045	General	The value of ‘d’ in the Eurocode crack calculation is incorrect when the section origin does not coincide with the centroid.	Build 24
NCR-11037	General	In some instances AdSec will not draw the section properly. Opening and saving the section will usually clear this problem.	Build 24
NCR-11031	General	When copying and pasting general reinforcement the rebar grade can get lost.	Build 24
NCR-11030	Analysis	In some cases with Eurocode the minimum ζ values is ignored and the calculated value used instead.	Build 24
NCR-11029	General	ACI 318M code options can in some cases return the wrong bar type.	Build 24
NCR-11028	General	The rebar strain limit for reinforcement to the Hong Kong Structures Design Manual 2013 is always returned as 0.05	Build 24
NCR-11024	Analysis	There is an error when using the CSA S6 code in the calculation of the area of concrete in tension which controls cracking, leading to incorrect code crack widths.	Build 19
NCR-11019	File I/O	When reading data from a text file the model will not run properly as some material properties have not been set. This problem can be worked around by opening the material wizards (concrete and reinforcement) and clicking OK which causes the materials to be re-established.	Build 19
NCR-11017	General	The template wizard for beam reinforcement does not properly enable the row spacing field when there are multiple rows of reinforcement.	Build 19
NCR-11010	General	Expansion of general reinforcement was not expanding lines, arc, etc. to individual bars.	Build 19
NCR-11003	Analysis	ACI 318 does not give clear guidance on how to calculate φ (strength reduction value) with composite (steel/concrete) sections. This change is to ensure that the standard concrete/rebar values are applied when the section if composite.	Build 18
NCR-11001	Analysis	Calculation of the crack width cover factor for EN1992/PD6687 returns a value of one instead of the factor based on actual and nominal cover.	Build 18
NCR-10998	General	Models using BS5400 (or related codes) and the default rebar stress-strain curve get corrupted when written, losing the material type. Re-establishing the rebar material after opening the file, avoids the problem.	Build 18
NCR-10993	General	Pressing the shift key in the Gateway while on a ‘section title’ causes a crash.	Build 18
NCR-10988	General	The neutral axis is not always drawn properly – particularly when it is outside the section.	Build 18
NCR-10987	Analysis	The rectangular stress block with EN1992 codes gives too low a plateau stress for high strength concrete – the η value is applied twice.	Build 18
NCR-10983	General	When editing reinforcement extra renforcement materials are generated in some cases, rather than using existing defined materials.	Build 18
NCR-10983	General	The option to display crack width values on a graphic view is not working.	Build 18
NCR-10975	Analysis	The Eurocode crack calculation gives wrong answers when a component strain plane or a concrete-only strain plane is applied to the section.	Build 17
NCR-10974	File I/O	The steel materials are not written properly to file causing the steel module to be unreadable when opening the file.	Build 17
NCR-10970	Analysis	When using Eurocode for SLS analysis the ζ factor is not calculated correctly leading to a wrong resultant strain plane.	Build 17
NCR-10968	General	Various data editing operations would cause the gateway tree to close up. The gateway now retains its expanded state.	Build 17
NCR-10961	Analysis	Eurocode crack width calculations can be wrong in the case when bars are equidistant from the section @lsquo;face’ and ‘side’.	Build 17
NCR-10961	General	The option to define a ζmin is not available for EN1992 / PD6687	Build 16
