This article reports a sub-domain method to analyze the dynamic interaction of soil-high-rise building group considering sit effect, which is the extension of the domain reduction method proposed by Bielak and his coworkers in the framework of the finite-element method, originally for building–soil–foundation interaction problems. The whole domain with high-rise building group is divided into two interrelated sub-domains, the external domain and the internal one. And the method contains two steps. In addition, the effect of the external domain to the internal domain is expressed by the equivalent forces which are put on the nodes of the interface between the two sub-domains in the second step. The formation of the equivalent force is attained according to the equation of motion. In the first step the free-field ground motion is calculated under the bedrock wave excitation, and all the nodal displacements are stored. Then the equivalent forces are calculated according the data in the first step, using the formulation of the equivalent force. In the second step a finite element analysis model of the sub-domain containing the internal domain and the high-rise building group is established, and the equivalent forces are put on the nodes of the interface. Later the seismic response of soil-high-rise building group can be calculated.

Cable Stayed Bridge

The dynamic characteristics of cable-stayed bridge will be affected greatly by soil action. In the paper, a spatial dynamic analysis model of a cable-stayed bridge was built by using the general finite element software ANSYS. The dynamic characteristics of the frequencies and modal shapes are investigated and compared with considering the pile-soil-structure interaction or not. From the analysis, the results indicate that if the pile-soil-structure interaction is taken into account, there will have a significant effect on the dynamic behaviors of bridge.

<p>The paper discusses results of shaking table tests on an in-scale high-rise building model. The purpose was to calibrate a dynamic numerical model for multi-hazard analyses to investigate the effects of floor acceleration. Accelerations, because of vibration of non-structural elements, affect both the comfort and safety of people. The research investigates the acceleration effects of both seismic and wind forces on an aeroelastic in-scale model of a multi-story building. The paper discusses the first phase of experiments and gives results of floor accelerations induced by several different base seismic impulses. Structural analyses were first performed on the full-scale prototype to take soil-structure interaction into account. Subsequently the scale model was designed through aeroelastic scale laws. Shaking table experiments were then carried out under different base accelerations. The response of the model and, in particular, amplification of effects from base to top are discussed.</p>

Seismic Vibrations

The reinforced concrete structures, not designed for seismic conditions, amid the past earthquakes have shown us the significance of assessment of the seismic limit state of the current structures. During seismic vibrations, every structure encountered seismic loads. Seismic vibrations in high rise building structure subjects horizontal and torsional deflections which consequently develop extensive reactions in the buildings. Subsequently, horizontal stiffness can produce firmness in the high rise structures and it resists all the horizontal and torsional movements of the building. Therefore, bracing and shear wall are the mainstream strategies for reinforcing the structures against their poor seismic behaviours. It is seen before that shear wall gives higher horizontal firmness to the structure when coupled with bracing however it will be another finding that in building model, which location is most suitable for shear wall and bracing to get better horizontal stability. In this study, a 15 story residential reinforced concrete building is assessed and analyzed using building code ACI 318-14 for bracing and shear wall placed at several different locations of the building model. The technique used for analysis is Equivalent Static Method by utilizing a design tool, finite element software named ETABS. The significant parameters examined are lateral displacement, base shear, story drift, and overturning moment.
