This piece SUPERSEDES C-L-SW14. This design example is not a complete building design. The remainder of the presentation will discuss: Sidewalk railing applications. For example, if the wood shear wall was designed using ASD, the design loads must be converted to LRFD to design the anchorage using ACI 318-08 because 318-08 exclusively uses Strength Design. With an intent to provide alternatives to the IRC prescriptive solution and the IBC engineering solution, APA has conducted a series of cyclic shear wall tests using a portal-frame design [4,5]. requires the understanding of diaphragm and shear wall flexibility and their effects on the horizontal distribution of forces through the structure. 4 (100+75+50+25) = 350 kips. To establish the maximum value of shear force that can be applied at the top of the shear wall, set [M OTM = (P v) (h. That is because moisture can often rise from the surrounding ground soil, into the concrete, causing problems over time. Here’s an example of what can happen when a conventional wall experiences the stress of an earth-quake or hurricane. The design methodology for concrete shear walls in 1963 ACI code (ACI 318, 1963) is based on working stress design; however, an ultimate strength design approach was also introduced. They are not full detailed calculations such as might be prepared for a real wall design but are limited to the calculation of earth pressure and bearing capacity, showing how the. It contains product data, engineering design information, installation and anchorage details. wall or wall segment behavior is governed by shear, shear drift ratio can be used as the deformation measure as defined in ATC-40. There are several design tools and standards to assist engineers, architects, and building officials with the design of shear walls. This can only be achieved, when resultant of soil pressure coincides with the resultant of soil force. For example, for wall i the relative rigidity is R i = 1/∆ i. Stiffening or bracing of the cripple wall to keep if from collapsing during seismic movement is a very important part of earthquake retrofitting. • If values in the analysis of the wall (i. 4 (100+75+50+25) = 350 kips. In the present study, it is conceived that different behavior may be permitted at different performance levels. This TEK is intended only to provide a general review of the pertinent allowable stress design criteria. the detailing required in order for the diaphragms and shear walls to maintain their rigidity and shape so that proper connections are maintained. For example, bolting two parts together can involve material properties and loading forces. The contents cover rigid and flexible diaphragms, shear walls, and detailed design examples. For example, in a large boiler made from sections of sheet metal plate riveted together, there is an equal and opposite force exerted on the rivets, owing to the expansion and contraction of the plates. com Design of Anchorage to Concrete Using ACI 318-08 & CSA-A23.
