Basic Structural Checklist For Building Type C3A: Concrete Frames/Infill Masonry Shear Walls /Flexib Mobile App
This is an older type of building construction that consists of a frame assembly of cast-in-place concrete beams and columns.
How does it work?
The floors and roof consist of wood sheathing on wood framing between concrete beams. Walls consist of infill panels constructed of solid clay brick, concrete block, or hollow clay tile masonry. The seismic performance of this type of construction depends on the interaction between the frame and infill panels. The combined behavior is more like a shear wall structure than a frame structure Solidly infilled masonry panels form diagonal compression struts between the intersections of the frame members. If the walls are offset from the frame and do not fully engage the frame members, the diagonal compression struts will not develop. The strength of the infill panel is limited by the shear capacity of the masonry bed joint or the compression capacity of the strut. The post-cracking strength is determined by an analysis of a moment frame that is partially restrained by the cracked infill. The shear strength of the concrete columns, after cracking of the infill, may limit the semi-ductile behavior of the system. Diaphragms consist of wood sheathing, or have large aspect ratios and are flexible relative to the walls. The Basic Structural Checklist For Building Type C3A: Concrete Frames/Infill Masonry Shear Walls /Flexible Diaphragms mobile app allows you to replace your paper structural checklist with a smartphone, tablet or desktop. The mobile form includes fields to document items such as date of inspection, structure/ building location, contractor details, records inspection note, and corrective actions and capture's contractor and inspector's signatures. Once the mobile app is filled out a secure PDF is generated. The PDF is easy to share, and a copy is stored in your account for your concrete records. You can also use the App Builder to personalize and customize this mobile form.
