STANDARD LOAD TABLE/OPEN WEB STEEL JOISTS, K-SERIES Based on a Maximum Allowable Tensile Stress of 30 ksi 13
OPEN WEB STEEL JOISTS, K-SERIES KCS JOISTS The KCS Joists: 1. Provide a versatile K-Series Joist that can be easily specified to support uniform loads plus concentrated and non-uniform loads. 2) Eliminate many repetitive load diagrams required on contract documents and allow some flexibility of load locations. KCS joists are designed in accordance with the Standard Specifications for K-Series Joists. Standard K-Series Joists are designed for simple span uniform load which results in a parabolic moment diagram for chord forces and a linearly sloped shear diagram for web forces. When non-uniform and/or concentrated loads are encountered the shear and moment diagrams required may be shaped quite differently and may not be covered by the shear and moment design envelopes of a standard K-Series Joist. KCS Joist chords are designed for a flat positive moment envelope. The moment capacity is constant at all interior panels. The top chord end panel is designed for axial load based on the force in the first tension web, which is based on the specified shear. A uniform load of 550 plf (8020 N/m) is used to check end panel bending. The web forces are determined based on a flat shear envelope. All webs are designed for a vertical shear equal to the specified shear capacity. Furthermore, all webs (except the first tension web which remains in tension under all simple span gravity loads) will be designed for 100% stress reversal. The KCS Joist load tables list the shear and moment capacity of each joist. The selection of a KCS Joist requires the specifying professional to calculate the maximum moment and shear imposed and select the appropriate KCS Joist. If a KCS Joist cannot be selected from the load table or if any uniform load exceeds 550 plf (8020 N/m) or if the maximum concentrated load exceeds the shear capacity of the joist, use double KCS Joists or select an LH-SERIES Joist. For the LH-SERIES joist, supply a load diagram. When net uplift loads, end moments or other external horizontal loads are a design consideration, these loads shall be provided to the joist manufacturer by the specifying professional. As is the case with standard K-, LH- and DLH-SERIES Joists, chord bending due to concentrated loads must be addressed. In the case of concentrated loads, the specifying professional shall handle them in one of two ways: 1) specify on the structural drawings that an extra web must be field applied at all concentrated loads not occurring at joist panel points, or 2) provide exact locations of all concentrated loads for which the joist manufacturer shall provide necessary reinforcement. Please reference Chapter Vl of SJI Technical Digest No. 9 HANDLING AND ERECTION of steel joists and joist girders (July, 1987). EXAMPLE 1 M = 625 in-kip (70.6 kN-m) R L =5600 lbs. (24.9 kN), R R =5000 lbs.(22.2 kN) Select a 22KCS3, M = 658 in-kip (74.3 kN-m) R = 6600 lbs. (29.3 kN) Bridging section no. 9 for L = 40 ft.(12192 mm) Use 22K9 to determine bridging and stability requirements. Since a standard KCS Joist can be selected from the load table a load diagram is not required. 14
