It is the initial problem to choose a reasonable layer-adding project in the layer-adding design for buildings. This paper is to prove, through living example, that choosing the truss structure between layers possesses well economical efficiency, and features space saving, ease of construction and good function of anti-earthquake at seismic regions. © (2014) Trans Tech Publications, Switzerland.

The boom of large-scale complex projects over the world leads the risk management more and more imperative, which achieves good economic and social benefits. The risks of safety, quality, progress and investment of the large complex project construction were discussed, and a large complex project performance evaluation model of risk control was established, which can accomplish the fuzzy evaluation of risk control performance. This method makes the project managers to control the risk of project construction quantitatively and qualitatively. © 2015 Taylor & Francis Group, London, UK. Source

Combined with the city of Baotou Arden Street underground passage pipe jacking engineering, using three-dimensional finite element software ANSYS to simulate the process of rectangular pipe jacking construction, this paper will emphasis on the influence of soil displacement around the construction site of the rectangular pipe jacking construction under dynamic loads. Through research, it got the rectangular pipe jacking construction sphere of influence of soil disturbance, and the variation in both horizontal and vertical direction, and compared with the measured data, proved that the numerical simulation has important guiding significance to the pipe jacking construction, will provide a reference for the future construction of similar projects. © (2014) Trans Tech Publications, Switzerland.

In this work, a rate-dependent model for the simulation of quasi-brittle materials experiencing damage and randomness is proposed. The bi-scalar plastic damage model is developed as the theoretical framework with the damage and the plasticity opening for further developments. The governing physical reason of the material rate-dependency under relatively low strain rates, which is defined as the Strain Delay Effect, is modeled by a differential system. Then the description of damage is established by further implementing the rate-dependent differential system into the random damage evolution. To reproduce the evolution of plasticity under a variety of stress conditions, a multi-variable phenomenological plastic model is proposed and the description of plasticity is then formulated. An explicit integration algorithm is developed to implement the proposed model in the structural simulation. The model results are validated by a series of numerical tests that cover a wide variety of stress conditions and loading rates. The proposed model and algorithm offer a package solution for the nonlinear dynamic structural simulations. © 2014, Springer-Verlag Berlin Heidelberg. Source
