Simplified method concrete flexible wall. While redundancy precludes elaborating upon a simplified method for concrete shear wall flexural design it is sufficient to say that most concrete shear walls are not loaded anywhere near their peak axial capacities. Apa s simplified wall bracing method an enhanced variation on the 2012 irc simplified wall bracing provisions section r602 12 gives builders an affordable streamlined approach to meeting wall bracing requirements that can be used for select single family construction designs in certain regions. In fact axial loads on shear walls are often so low that they can simply be characterized as vertical beams. Walls can be designed using simplified design methods given in codes such as the australian concrete standard as3600 09 the eurocode 2 ec2 04 and the american concrete institute code.
The purpose of this document is to provide an acceptable design method and theory for the. 2012 irc simplified wall bracing provisions 4 28 2015 15 43 narrow bracing h methods 8ꞌto 10ꞌ 16 method pfh h 4 h 8ꞌto 10ꞌ method pfg 2012 irc simplified wall bracing 44 lateral support and stem walls use section r602 10 8 2 to add bracing to rafter or truss areas to complete the load path from roof sheathing to the bracing unit. Partially grouted reinforced masonry shear wall design. With the apa simplified wall bracing method the builder only needs to consider four walls a few simple calculations and one bracing method.
This assumption is based on installation recommendations of a system that is placed on soils and a flexible leveling pad of well compacted gravel or unreinforced weak concrete that can crack if necessary. Srw structures are free standing and able to displace horizontally at the base and yield laterally through the height of the wall. We will cover a simplified design method for designing masonry shear walls. Traditional wall bracing must consider many wall lines wall line spacing off sets in wall lines lengths of each wall line and many various multipliers and bracing methods.
I don t have a direct reference at this time however the reinforced masonry engineering handbook 6th edition and msjc tms402 05 08 11 could be referenced. A permanent wall will usually incorporate concrete lagging with an architectural finish. Apa simplified wall bracing method. Under that method the greater the assumed soil pressure or the taller the wall the thicker the wall must be.
Founded in 1904 and headquartered in farmington hills michigan usa the american concrete institute is a leading authority and resource worldwide for the development dissemination and adoption of its consensus based standards technical resources educational programs and proven expertise for individuals and organizations involved in concrete design.
