ACI 318 1 and AS3600 2 are inadequate for designing these walls as they are often outside the limits set by the codes.

. Design of reinforced concrete non-load bearing shear wall. Section 1483 of the alternative design of slender walls for ACI 318-02 as well as 05 and 08 states that the moment at the midheight section of the wall due to factored loads and P-Delta effects Mu can be obtained by iteration of deflections using equations 14-4 and 14-5 or by direct calculation using equation 14-6. Slender concrete tilt-up slender bearing wall incorporated into tilt-up construction over the past 60 years.

The wall is restrained at the top edge and the roof. 2 Exterior Load Bearing and Non Loadbearing single Wythe Masonry Walls.

The glass glazing curtain-wall systems interface with the SlenderWall system in a similar fashion as with thicker traditional architectural precast concrete panel systems. Concrete tilt-up slender bearing wall design example using ASDIP CONCRETE. B8-Plain panel on isolated footing or pier design example p.

Concrete Slender Bearing Wall Using ASDIP CONCRETE. For an element to be described as a reinforced concrete wall the length to thickness ratio should be equal to or greater than 4 Clause 961 Eurocode 2. The concrete wall panel element allows you to easily model analyze and design concrete walls for in plane loads for the codes defined below.

V r 100 kips. The design of shear walls involves providing adequate cross-section and reinforcements to resist bending shear axial and twisting forces due to gravity and lateral loads. For example if you enter 025 and the wall weighs 80 psf then a 2000 psf out-of-plane load will be calculated and applied to the wall using the load combination factors for E.

With these type of construction the walls used are often very slender and made with high-strength concrete. An 8-inch thick concrete wall f c 4000 psi spans vertically 24 feet. Wall is exposed to wind pressure and it supports eccentric gravity loads.

Section 144 Walls designed as compression members appears to be the most appropriate method for this example. V 2 25 kips. The design example Slender Reinforced Concrete Wall DesignSolid Wall with Out-of-Plane Loading Due to Wind works through calculations for a wall design following the provisions of ACI CODE 318-19 Building Code Requirements for Structural Concrete and Commentary.

One curtain of vertical bars is at the center of the wall with 5 12 inches assume effective depth d 4 inches. Present Tall Wall Design Examples 2. The most economical design is a flush-faced design where the window system is in alignment with the exterior face of the SlenderWall system see Drawing A-2 in the Typical.

It provides designers with unique and limitless design flexibility and function. An example using this method can be found in PCA Notes see the Additional Reading section below. Precast Concrete Bearing Wall Panel Design Alternative Design Method Using ACI 318-11 A structural precast reinforced concrete wall panel in a single-story building provides gravity and lateral load resistance for the following applied loads.

ACI 318-05 Design data. Weight of 10DT24 468 plf Roof dead load 20 psf Roof live load 30 psf Wind load 30 psf The 10DT24 are. Design of plain concrete walls shall be in accordance with Chapter 14.

EXAMPLE OF SHEAR W ALL DESIGN T O EC2. SlenderWall provides all of the permanency and flexibility of traditional architectural precast but benefits from a 23s savings in weight and an integrated interior stud frame. 68 CHAPTER 1-INTRODUCTION Tilt-up concrete buildings have been constructed in North America for over 100 years but it was not until the late 1990s that ACI 318 specifically addressed the requirements for design of slender concrete walls.
