Abstract:

The local series system with typical common plate rubber support/pier in highway reinforced concrete girder bridge is the object of the current research. The finite element numerical simulation method is used to study sensitive parameters – the mechanical properties of the series system under the horizontal load. The simulated results show that the interface bonding strength between the bearing and adjacent structure is reduced; the equivalent shear deformation and the horizontal force of bearing under horizontal load change insignificantly with the increase of horizontal displacement.

Abstract:

Increase in the number of floors of high-rise buildings increases both vertical and horizontal loads, but at the same time increases the share of the total horizontal load stress in their individual load-bearing members. This stress must always be verified. At the same time, the height of the building also increases the horizontal deflection, resulting in increased requirements for the horizontal stiffness of the structure. The use of high-strength materials resulting in a reduction of dimensions of the load-bearing members and the weight of the building, results in a large slenderness of high

Flexible Berthing Pier is a port structure that absorbs, partly or totally depending on self- deformation, the ship berthing energy and the ship rolling energy caused by the wave. Flexible berthing pier mainly sustains the horizontal load. Present methods to calculate the horizontal bearing capacity of pile foundation consist of P-Y curve method, NL method and m method. P-y curves method is one kind of nonlinear subgrade-reaction methods; it considers the nonlinear character, layer character, different kinds, and load kinds of ground soil. Starting from the concept of spring joint in Newmark m

This Currently, researches on formwork supporting system are mostly based on integrated stability, while the contribution of the cooperative bearing effects of the formwork supporting system and the concrete floor to the reliability of a structure is ignored. In this paper, the necessity of the existence of the formwork supporting system in the construction process of a structure’s roof boards is established by analyzing the cooperative effects of the formwork supporting system and the concrete floor of a subway transfer station under construction through double nonlinear numerical method.It i

Abstract:

In the course of the exploitation of building structures frequently situations turn up, in which the structure is not adequately used (it may, for instance, be exposed to considerably greater loads than previously been intended). In the state of an unforeseen overload of the structure, essential reserves of their load-bearing capacity may be disclosed in the case of the self-acting work as a flexible strand. The paper presents the results of investigations concerning the influence of the parameters of reinforcing steel on the mechanism of the destruction of six single-span models of narrow rei

Different laid modes of aluminum alloy section bars and their mortise and tenon joints were bending tested, and their mechanical properties were compared, in order to research on the influence that forming a mortise and tenon joint brought to the original bars. Opening a hole laterally and inserting another shorter bar in the hole changed the bending properties and energy absorption capacity of the original bar. In horizontal laid mode, the mortise and tenon joint was weaker than the original bar when bearing bending load, but it was stronger in vertical laid mode. Weld beads of the mortise an

Abstract:

When a structure is excited by an earthquake ground motion the input energy may be reduced by inelastic action or by supplemental damping devices. If the seismic energy dissipation can be achieved by means of separate non-load bearing supplementary damping systems, the structure itself can remain elastic providing a continuing serviceability following the design level earthquake. This paper illustrates the advantages of using added, or supplemental, damping in structures. The control system consists of passive friction dampers installed in the ground floor of the structure using tendons

Biomechanic conception of implant choice for primary total hip replacement in osteoporotic femur neck fractures is presented. Criterion for the choice is a localization of load-bearing surface of dense structure in acetabulum roof zone, i.e. sursile. Absolute indications to total hip replacement, use of bipolar and unipolar hemiprostheses are determined depending on the direction and deviation degree of sursile from horizontal axis of pelvis.

The combine behavior of masonry arches and walls, which exert an unloading effect on the bearing arches, was analyzed. The finite-element model of the Wallen-Delamot arch was designed for the effect of the load of the overlying masonry. The load action was taken into account both from a combined finite element model with a rigid connection of the arch and overlying masonry, and from the gravitational load transferred to the arch. The dependences of the maximum acting stresses in the arch on the modulus of elasticity of the overlying masonry are constructed, reflecting the behavior of the damag

For a pile foundation design, the value of proportional coefficient m to define the soil horizontal resist force is a significant parameter. However, different geological conditions and experimental environment have led to different m values. In this paper, an in situ test is firstly carried out on the horizontal bearing capacity of large-size precast square-piles. The piles deformation is then derived by using the optimization method from the measured data. Secondly a back analysis model is established to calculate the m value by using the simplex method, which reveals the evolution rule of t

Reinforced concrete (RC) structures have their own weight, earthquake, wind, dead loads, live loads, creep, etc. throughout their service life. They are exposed to internal and external load effects. In order to meet the horizontal forces such as earthquake and wind from these loads affecting the structure, shear wall structures with high lateral rigidity are needed. Therefore, shear walls are one of the most important structural elements that can resist earthquake forces due to their high lateral rigidity and load bearing capacities.
