Our joists and girders are engineered and manufactured in accordance with the specifications of the Steel Joist … Listed steel joist manufacturers, suppliers, dealers & exporters are offering best deals for steel joist at your nearby location. If not then select a valid joist for the given span. SkyCiv Engineering. Because of the limitations on analysis, the joist should not be experiencing any resultant lateral forces. KCS joist chords are designed for a flat positive moment envelope. Open web joists are designed and fabricated per the Steel Joist Institute (SJI) specifications. RedBuilt Open-Web Trusses offer a variety of solutions for a broad range of challenges.

The joist must be anchored also to … Common bearing length for a K-Series joist on Masonry is 4-6″ and 2-1/2″ on steel. Steel Joists & Joist Girders Open web-steel joists are an engineered, truss-like construction component used to support loads over short and long spans alike. If any other load type or variation is used, Structural 3D will generate a error message. K-Series Joists are standardized regarding depths, spans, and load-carrying capacities. The depth of the bearing seat at the ends of underslung LH- and DLH-Series Joists have been established at 5 inches (127 mm) for chord section number 2 through 17. The LH- and DLH-Series have been designed for the purpose of extending the use of joists to spans and loads in excess of those covered by Open Web Steel Joists, K-Series. There are 63 separate designations in the Load Tables, representing joist depths from 10 inches (254 mm) through 30 inches (762 mm) in 2 inch (51 mm) increments and spans through 60 feet (18,288 mm). The standard depth at the bearing ends has been established at 7 1/2 inches (191 mm) for all Joist Girders. Longer spans will require LH and DLH joists. "the easi-joist® metalweb floor system with a rigid strongback reduces vibration and improves the overall performance of the floor" Therefore steel bar joists or also known as open web steel joists for framing floors and roofs offer many advantages when compared to a wood truss or steel beam system. Some other shapes, in addition to the parallel top and bottom chord, are single slope, double slope, arch, gable and scissor configurations. It occurs when the proposed maximum depth of the joist is too small for the selected joist span and load case. The key is knowing the difference between situations where more is not necessarily better and those where more is … K Series … Designs based on ASD and LRFD can produce significantly different results, especially Factored vs. Unfactored. Centroid Equations of Various Beam Sections, How to Test for Common Boomilever Failures, Check that your proposed joist designation has been inputted correctly and in the correct format, specifically that the joist series is inputted as a CAPITAL letter (K, LH, DLH vs k, lh, dlh). Powerful, web-based Structural Analysis and Design software, Free to use, premium features for SkyCiv users, © Copyright 2015-2020. The major benefit of metal web joists is the open web which allows easy installation of the plumbing and electrical services. Check that the magnitude and units of your applied load is correct and intended. SkyCiv Structural 3D currently supports the design of joists in accordance with the Standard Load Tables¹. These concentrated loads are considered to act at the panel points of the Joist Girders. For LH/DLH joists, common bearing length is 6-12″ on masonry and 4″ on steel. Note: Joist sizes can be written in/edited and individually checked for design using the ‘Check’ button. A valid joist cannot be selected from the SJI loading tables. Open Web Steel Joists, K-Series, were primarily developed to provide structural support for floors and roofs of buildings. When conditions such as this arise, a KCS joist may be a good option.[1]. When filling in the form regarding the joist chord and web member properties, it is recommended that the field measurements be taken with a micrometer rather than a tape measure, since thicknesses can vary by as little as 1/64 inch. To commit that joist to your member, either click on the blue ‘Commit Changes’ text or the gray arrow to the right of the field. The LH- and DLH-Series have been designed for the purpose of extending the use of joists to spans in excess of those covered by Open Web Joists. Lengths are offered in two foot increments due to their 24″ trimmability.
