in which L is the critical length for distortional buckling or the distance between restraints which limit rotation of the flange part of the section. The elastic stiffness term for the web is modified to take into account the more flexible perforated part of the web. Thus the perforated part of the web is replaced by a plate of equivalent...

Table 3 gives the maximum bearing capacity evaluated with EC4, LRFD and the model proposed. For the latter the strength of the columns is penalised to take into account the effect due to the slenderness of the columns through the ~ coefficient proposed by EC4. NplR and P= the bearing capacity of the composite columns according to EC4 and LRFD...

Most of the steel hollow sections manufactured in Australia are in Grade C350 and C450 (minimum yield stress of 350 and 450 MPa). The width-to-thickness (H/t) limits are lower for C450 RHS than those of C350 RHS (Zhao and Hancock (1991. where H is the overall width or depth (whichever is larger) of an RHS and t is the thickness...

convergence of the solution of the neutral axis orientation for all cross-sectional conditions. The results agree well with the test results. The bending moment capacity of a composite column of asymmetric polygonal section is then checked and the required bar diameter is successfully designed. The work presented in this paper is the result of a collaborative effort between the Department...

These economies have largely accounted for the dominance of composite steel frame construction in the commercial building sector in the UK in recent years. Composite construction of steel frames with profiled steel decking to support floor slabs is now common in multi- storey construction, but the use of precast prestressed concrete hollow core units (hcu' s) in conjunction with the...

Plate Thickness. A comprehensive numerical programme was conducted on the tested specimens. The initial stages of numerical modelling have been concentrated on the definition of the geometric model, associated constraints and the constituent material properties. Subsequent selection of finite element types in the computer program will determine the mathematical model applied to achieve solution convergence. A wide range of parameters...

Figure 8 and 9 illustrate the longitudinal movement and range of longitudinal movement of Tsing Ma Suspension Bridge at the expansion joint at the Tsing Yi Abutment. It is noted that the trend of the movement, when converted into effective temperature of the bridge, can be readily represented by a straight line. The gradient of the fitted straight line for...

The servo accelerometers are of the brand Allied Signal Aerospace Q-Flex QA700. Three different types of arrangement for acceleration measurement were used in the system, namely AccT, AccB and AccU as indicated in Fig. A total of 12 uni-axial accelerometers were located at the four sections of the bridge deck. At each section, there are two accelerometers measuring acceleration in...

In this paper, a finite element formulation for vibration analysis of large-diameter structural cables taking into account bending stiffness is developed. A numerical verification is made by analyzing with the proposed method the modal properties of a set of cables with different degrees of bending stiffness and sag extensibility and comparing them with the results available in the literature. The...

vertical dynamic response of the undamped main span cable at the cable midspan when a vertical harmonic excitation is exerted at the same position. By interchanging the input and output roles in the training of the network, a functional mapping for the inverse relation can be directly established using the neural network which then serves as a tension force identifier.....

The first three theoretical natural frequencies of the main beam bridge was calculated as f. The U-shape aluminum track was glued to the upper surface of the main beam as a guide for the car.. Seven photoelectric sensors were mounted on the beams to measure and check the uniformity of moving speed of the car. Seven equally spaced strain gauges...

Figure 6 shows that the ductility factor/1 p of the pier increases with the increase of yield force ratio Qy/Py for most values of Kbl/Kp, while the ductility factor/1 b of the isolator decreases. In this case, the maximum value of /.t p is obtained for the yield force ratio of Qy/Py=0.2 that is the smallest one. It can be...
