Bolt Diameter

In lattice angle steel transmission tower, as the bolt diameter is small and member connection is relatively thin, lower clamping force is commonly used in bolted joint. It is common in lattice tower during full tower tests, joint slippage occur even under design load. However, traditionally trussed beam hybrid finite element model without explicitly considering slippage effects has been widely used in the analysis of the tower. In this paper, the HD-1 tower was experimentally studied under various static load cases, and several numerical models with including joint eccentricity and slippage are established. After comparing the theoretical analysis results and the experimental results, the following conclusions are presented: joint eccentricity almost has not effects on leg member axial force; Among all the studied load cases, joint slippage effects the leg member force most under torsional condition than the other load conditions; Numerical model with including joint slippage effects yield much better axial force results in leg member compared with experimental test results.

Single-layer hyperbolic paraboloidal latticed shell dome is adopted in the gymnasium of China University of Petroleum. And the center part of the dome employs crossed web bars in order to increase stiffness of the structure. The 1:12 scale model has been made according to the construction drawings, and the mechanical properties of the model are studied under self-weight load and design load. The regularity of the members' axial force and joints' displacements are obtained. And the results show that the deflection of dome under design load conforms to the requirement of specifications, which verified the correctness of the structure design. It is found that there is no overall instability and local instability, and the behavior of the structure is almost linear.
