• The columns can be braced or un-braced in X and Y direction. A click of the respective radio button makes the Column braced or Un-braced.
• Up to six loading cases can be considered for the design of each column.
• Each RectCol data file can hold design information for up to 200 columns. The file size, when maximum, is about 800 KB.
• A pull down combo box displays a scrollable list of all user descriptions for each column. This permits re-display and re-design of each column with ease and rapidity at a later stage.
• Auto analysis checks the design of all columns by one click of a command button. If required, the results for each column can also be printed by the Auto analysis.
• Fail-codes for the design check of each column and its 6 loading cases are shown in red cell pattern. The use of red pattern makes the failing columns apparent at a glance. The Fail-codes are also shown in the "Store" worksheet, after the Auto analysis of all columns as a batch.
• When designing un-braced columns, floor displacement can be also be specified for each column. As described in Clause 3.8.3.8 of the code, this deflection is used for calculating the deflection induced moment in the column design.
• By the click of a radio button, the end connection for each column can be specified as being Rigid, Semi-rigid or Pinned. For un-braced columns, the top connection can also be a Free connection. The above 4 connections respectively represent type 1, 2, 3 and 4 end connections described in Section 3.8.1.6.2 of the code. These connections help establish the factor for effective column height from Table 3.19 and 3.20 of the Code.
• RectCol is a one-page document for the design of all rectangular columns using BS8110. The screen and output layout has been so arranged that the user or a checking authority can check all results by hand calculations.
• The program uses an interactive technique to calculate moment capacities of a column section corresponding to its balanced failure load and applied axial loads for each of its six loading cases.
• The column shape and position of bars are plotted in two separate diagrams. One diagram is for bending about the X-axis and the other for the Y-axis. In each diagram, the position of neutral axis is also shown.
• RectCol incorporates the use of default values for new columns. The user can set these to any desired values. They are f_cu, g_mc, g_ms, section width, section depth, cover to the centroid of steel, height in X-direction, height in Y-direction and the area of steel reinforcement bars.
