: In this study a tall G+8 storied curved in plan (comprising an external and internal curved facade) has been analysed for wind acting in specified directions using STAAD pro v8i.For the curved profile, the wind load component has been calculated for each radial beam line. The combination of static load and wind load are taken into consideration. In the first case, the wind has been assumed to act towards the centre of the arc of the circle and in the second, away from the centre. The post processing reverberation in terms of bending moments, shear forces and support reactions has been studied in relation to the wind directions. Due to the effect of wind load on the structure, the storey-sage variation of the result with respect to different parameters are to be compared. The stiffness of the structure as a whole is expected to vary with the changed direction of the wind. The result would result in a parametric study of the effect of wind direction on curved profile. The orientation of the curved structure with respect to the direction of wind load has been studied.

Computer programs for calculation the strength of statically determinable double-support and cantilevered I-beams are based on the previously proposed concept of using safe factor spaces of I-beams and significantly simplify and speed up the calculation process. The programs are created in the Mathcad system and illustrated by a numerous of examples. Programs use unified beam schemes, which geometric and power parameters are set by the user. All further calculation is performed by computer in automatic mode. The computer determines the beam support reactions, builds its specific calculation scheme, depicts the diagrams of the shear forces and bending moments, determines the minimum of I-beam size that satisfies the strength conditions for normal, tangential and equivalent stresses. The completed software developments can be recommended to the students and engineers to use for educational purposes and engineering practice. It is recommended to add more functionality to the programs - to determine the deformations of beams - deflections and angles of rotation of sections, which will significantly expand the range of the considered tasks.

The problem of large deflection of a rectangular plate resting on a Pasternak-type foundation and subjected to a uniform lateral load has been investigated by utilizing the linearized equation of plates due to H. M. Berger. The solutions derived and based on the effect of the two base parameters have been carried to practical conclusions by presenting graphs for bending moments and shear forces for a square plate with all edges simply supported.

The Ministry of Transportation of Ontario was interested in a rehabilitation strategy that could be used to address deep-seated rutting issues encountered on its 400-series highways. A precast concrete inlay panel (PCIP) rehabilitation design was developed and constructed involving the installation of precast panels into partially-milled asphalt pavement. Sub-surface instrumentation was installed at the PCIP–asphalt interface including earth pressure cells and moisture sensors installed in six instrumentation clusters. This instrumentation has been monitored to gather information regarding the PCIP trial installation. Readings from the moisture sensors indicate that water penetrates beneath the PCIPs in precipitation events, though these moisture levels recede under dry conditions, indicating that the water can exit the sub-slab area. Static load testing using a fully-loaded gravel truck was used to determine the different support reactions caused by different loading configurations. Higher loads were generally found beneath the joints in the two loading situations studied.

This paper presents some results concerning the vertical response of two different ships sailing in regular and irregular waves. One ship is a containership with a relatively small block coefficient and with some bow flare while the other ship is a tanker with a large block coefficient. The wave-induced loads are calculated using a second-order strip theory, derived by a perturbational procedure in which the linear part is identical to the usual strip theory. The additional quadratic terms are determined by taking into account the nonlinearities of the exiting waves, the nonvertical sides of the ship, and, finally, the variations of the hydrodynamic forces during the vertical motion of the ship. The flexibility of the hull is also taken into account. The numerical results show that for the containership a substantial increase in bending moments and shear forces is caused by the quadratic terms. The results also show that for both ships the effect of the hull flexibility (springing) is a fair increase of the variance of the wave-induced midship bending moment. For the tanker the springing is due mainly to exciting forces which are linear with respect to wave heights whereas for the containership the nonlinear exciting forces are of importance.

The response analysis of a large cable net bearing wind load is conducted by the nonlinear finite element method. First, the form-finding calculation of the cable net structure is carried out to find an equilibrium state which can make the pretensions and sags of the wires meet the given requirements. Then the static analyses of the finite element model of the cable net structure under different wind loads are conducted to assess whether the cable net structure meets the requirements for strength. The work of this paper establishes the foundation for the design of a large cable antenna.
