D1.G.8 Tabulated Results of Member Design

For CODE CHECKING and/or MEMBER SELECTION the output results are printed as shown in the previous section. The items are explained as follows:

1. MEMBER refers to the member number for which the design is performed.
2. TABLE refers to the size of the PRISMATIC section (B X D or ZD X YD).
3. RESULT prints whether the member has PASSed or FAILed.
4. CRITICAL COND refers to the CLAUSE or FORMULA NO. from the TIMBER CONSTRUCTION MANUAL (3rd. Edition, AITC-1985) which governed the design. See following table:

Table 1. Critical conditions evaluated per AITC code
Critical Condition Governing Criteria
Clause 5-19 Axial Compression and Bending with MINIMUM ECCENTRICITY.
Clause 5-18 Axial Compression and Bending
Clause 5-42 Axial Tension and Bending
Clause 5-24 Horizontal Shear
Clause 5.40 Lateral stability for net compressive stress in case of Tension and Bending.
5. RATIO prints the ratio of the actual stresses to allowable stresses for the critical condition. This ratio is usually the cumulative ratio of stresses in the interaction formula. In case of shear governing the design, it means the ratio of the actual shear stress to allowable shear stress. If this value exceeds the allowable ratio (default 1.0) the member is FAILed.
7. FX, MY and MZ provide the design axial force, moment in local Y axes and moment in local Z axes respectively. FX value is followed by a letter C or T to denote COMPRESSION or TENSION.
8. LOCATION specifies the actual distance from the start of the member to the section where design forces govern in case BEAM command or SECTION command is specified.

OUTPUT parameters that appear within the box are explained as follows:

1. MEMB refers to the same member number for which the design is performed.
3. LAM refers to lamination thickness provided in the input or assumed by the program. See INPUT PARAMETERS section.
4. LZ, LY, LUZ and LUY are the effective lengths as provided or calculated. See INPUT PARAMETERS section.
5. JZ and JY are the modifiers for the P-DELTA effect about Z-axis and Y-axis respectively. These are calculated by the program.
6. CDT, CSF, WET, CCR, CTM are the allowable stress modifiers explained in the INPUT PARAMETERS section.
7. CFZ and CFY are values of the size factors in the Z-axis and Y-axis respectively. CLZ and CLY represent the factors of lateral stability for beams about Z-axis and Y-axis respectively. These values are printed to help the user see the intermediate design values and re-check the design calculations.
8. fa, fbz, fby, fvz and fvy are the actual axial stress, bending stresses about Z and Y axes and horizontal shear stresses about Z and Y axes respectively. If the bending moments about both axes are less then the eccentric moments based on min. eccentricity then bending stresses are calculated based on the min. eccentricity . Refer DESIGN OPERATIONS section for details.
9. FA, FBZ, FBY, FVZ, and FVY are the final allowable axial, bending (Z and Y axes) and horizontal shear (Z and Y axes) stresses. See D1.G.2 Allowable Stress per AITC Code for details.
