Selecting Auto Spacer from the Spacer drop down menu, allows the software to calculate a suitable spacer thick-ness based on a target Load Transfer Factor (Note the lowest LTF when using bolt tensioning tools is 1.15). To solve bolting groups in general: 1) Find the bolt group centroid 2) Determine directional vectors for each bolt with distance Rn 3) Calculate direct shear load for both the weight and applied load (Fv) 4) Calculate Reaction Moment (M) at the bolt group centroid. from precision medical instruments to high-performance robotic solutions, FUTEK products are designed to work in the most demanding environments even on Mars. Last. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. Calculate bolt design stress and design load from bolt diameter and yield stress or proof stress. Accuracy. Bolt Load Calculation Software Hydratight introduces Informate: the next generation of software that provides bolt loads and tool pressures on a huge range of flanged joints and clamped connections. Tension tooling, powertrain couplings, and accessories designed for power generation applications. Bolt load is calculated from the design stress (SAE, ISO or ASME), bolt size (UNC, UNF, BSW or ISO) and the tensile area (ANSI or ISO threads). 8) NOMINAL BOLT SLIP LOAD - This is the nominal slip load shear loads applied to the joint should be below this value. Email * Website. Too much clamping force can also cause severe problems. Step 1 - Enter Information. Single. Finding Tension Loads on Fastener Group This procedure is similar to the shear load determination, except that the centroid of the fastener group may not be the geometric centroid. Proper amount of tensioning of the bolts is vital. Definition of the algorithm Connection Calculator Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws and wood screws per the 2015 NDS . Actually what I do not understand in ASME is that the bolt load used for design seems different from the true bolt load (as the one I describe just above). Boltplus Bolt Load Calculation is a free app and what makes it different from similar apps on the market is the speed, ease of use and ability to save all the calculations against a project. Shear Capacity at 160N/mm THREADS IN SHEAR PLANE. BoltUP - Our online bolt load calculator; Informate - Our advanced calculation and procedure software; IDMS Integrity Data Management System - The complete package for managing Bolted Joints from cradle to grave. Product Lines. F v,Ed is the applied shear load and F v,Rd is the shear resistance of the bolt. K constant d diameter of bolt (m, in) F axial bolt force or load (N, lb) The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. BOLT LOAD CAPACITY TABLES TO BS5950 PART 1, 2000 THE ULTIMATE LIMIT STATE (ie FACTORED APPLIED LOADS) GRADE 4.6 BOLTS In Grade 43, bearing capacity = 460N/mm, for e 2d. In the continuation, the paper briefly presents the model for operating bolt load calculation and the method for the calculation of structure elasticity and stiffness matrices and presents a comparative analysis of the results obtained through different calculations and measurements. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. Tension elements: Elongation due to axial load Calculator: Calculates elongation (as well as stress and strain) for prismatic elements subject to axial force.. Wood tension element capacity Calculator: Calculates capacity of a wood tension element based on allowable tension on net area (reduced by bolt holes) and, if desired, row and group tear-out.
