In addition to the requirements of this Standard, it is necessary that the design be carried out in accordance with the provisions of applicable Building Codes governing fire resistance.

Table 1 illustrates the spacing, both in general terms and for a specific exam- ple, when the minimum reinforcing ratio, IP-min, is 0. Start Webshop Product catalog Product presentation. In Figure 5, the compressive stress in the concrete, Cc, is calculated using the following equation: This example highlights code based selection of drop panel dimensions, analysis process of non-prismatic slab with drop panels, the crucial role of drop panels in resisting two-way shear at columns, and detailed deflection calculations.

Note that Pr,max is reduced not only by the strength reduction factors but also by an additional factor of 0. Enter the email address you signed up with and we’ll email you a reset link. In all of the hand calculations and the reference used illustrated above, the results are in precise agreement with the automated exact results obtained from the spColumn program.

Table 1 – Comparison of Results.

Pure compression Point 2: Help Center Find new research papers in: If no specific edge member dimensions have been specified by the user, the program assumes that the edge member has the same width as the wall, and the program determines the required length of the edge member.


In these planes, the maximum concrete strain is always taken as Forces in the concrete and steel 9. This iterative procedure continues until Ast and Asc are within the allowed steel ratios for all design load combinations. Further differences in the interaction diagram in both directions can result if the column cross section geometry is irregular.

Maximum factored axial load resistance. Similarly, the largest of the eight reinforcing ratios used is that specified in the shear wall design prefer- ences as Section Xsa IP-max. Slenderness effect for columns in a sway frame is evaluated by designing a first story exterior column in multistory reinforced concrete building 22″ x 22″ column section. The T-shaped formation comprises the basement retaining wall Tee flangethe stem serving as the shear wall Tee weband the first building column.

Typically, negative moments over supports govern the design of reinforcement and any reduction in the required area of steel at the supports is favorable due to savings in materials, labor, and construction time and effort.

The strength under pure axial tension is computed by assuming that the section is completely cracked through a23.33-94 subjected to a uniform strain greater than or equal to the yield strain in tension. Otherwise, there will be a moment associated with both Pr,max and Pt,max.

Summary and Comparison of Design Results. Design Condition 2 Design condition 2 applies to a wall pier with user-specified edge members at each sca of the pier.

The pier geometry is de- fined by a length, thickness and size of the edge members at each end of the pier if any. Log In Sign Up. A structural reinforced concrete tilt-up wall panel provides gravity and lateral load resistance in a multi-story building is investigated using the procedure in ACI and compared with the results of spWall engineering software program from StructurePoint.

Also for a23.33-94 loading combinations involving SRSS, the Pleft-top and Pright-top forces are obtained first for each load case before the combinations are made.

StructurePoint – Design Examples

Half of the remaining number of specified points on the interaction curve occur between Pb and Pr,max at approximately equal spacing along the Pr axis. A structural reinforced concrete continuous beam at an intermediate building floor is analyzed and designed Including structural analysis, flexural design, shear design, and deflection checks and the results of hand csaa are then compared with numerical analysis results obtained from the spBeam engineering software program.

The appropriate expression of these two terms was provided previously. Home Software spSlab v5. Buy Standards Purchase the standards and standards-based products you are looking for.

Then we describe how the program designs piers that are specified by a Section Designer Section. Similar equations apply at the bottom of the pier.

We recommend that you use 24 interaction curves or more to define a three-dimensional interaction surface. Structural Analysis of Reinforced Concrete W23.3-94. The benefits of a subscription: Skip to main content Skip to footer.

The width csw the variable length edge member is equal to the width of the wall. The maximum tensile reinforcing to be packed within the tp times B1 concrete edge member is limited by: When creating a single interaction curve, the program in- cludes the points at Pb, Pr,max and Pt,max on the interaction curve.

The default value is 0. Additionally, different modeling and analysis techniques using spWall engineering software program to investigate and design tilt-up wall panels with openings a23.-394 discussed.
