With the development of tall building, the requirements for the structural design and construction of building becomes higher and higher, especially the design of the late-poured band in underground structure and the construction measures in the projects. In this paper, taking a high-rise frame structure...

This paper proposes a new method in which the number of dependent constraints is determined based on the transformation parameters of the coordinate systems associated with the links of a mechanism; the number of homonymous parameters that are equal to zero is subsequently used to determine the overall...

The results demonstrate that the effect of elasticity in plastic zone on elastic-plastic fields is remarkable in many cases, while elastic volume deformation in plastic zone generally has been omitted in the solution procedures of the classical plastic theory due to the mathematic problems. The analytical...

Reliability analysis of uplift stability based on the first order second order method for digged foundation in gravel soil has been made by non-dimensionalization for ultimate state equation and combining with the test results. The ratio of test value to calculated uplift capacity Kp that reflects the...

The desiccation cracks can be often observed on dry-out soil surfaces. These cracks have a net-like structure and tessellate the surface of the material into polygonal cells hierarchically. The size and the shape of these cells on the final pattern change systematically depending on the specimen thickness...

According to the characteristics of the shell body and the Deformability of 30CrMnSi, the near-net forging technique is obtained by choosing the preforming process, formulating the drawing of cold ironings and the drawing of warm forgings, designing the cold ironing die set and the warm forging die sets....

The electric arc furnace is an important smelting equipment in modern iron and steel enterprises. However, the load of electric arc furnace is a typical impactive and nonlinear load, and it has a huge effect on power system, electrical equipment and enterprise production. Based on the theory of peak...

In this paper, we studied the control effect of irregular structures with translation-torsion coupling response under earthquake loading by using semi-active control method. On the base of traditional resistance design method, we couple magneto-rheological fluid damper (MR) and tuned mass dampers (TMD)...

To study the dynamic effect of the prestressed braced steel moment frame caused by the sudden loss of a cable bracing, the instantaneous loading method is adopted to calculate the dynamic response of the remaining structure during and after the rupture of the cable with the simplified theoretical model...

Cellular concrete (CC) is a foamed mixture of cementitious materials, fine sand, and water, which once hardened results in a consistent, lightweight concrete containing millions of evenly distributed, uniformly sized macroscopic air-voids of approximately 0.1 to 1 mm size. In the present study, cellular...

In the economic development of port-surrounding regions, there exists a strong correlation among port, city and industry. They depend on each other and influence each other. To study regional economy in port, we must take port-industry-city complex system (PICCS) as the research object. By means of the...

The Fukushima accident pushed nuclear energy into dark criticism. Five years after, Japan is still faltering in its response to phase out nuclear. Global generating electricity from nuclear has decreased. Unfortunately, capital costs for renewables continue to fall, but costs of nuclear power keep rising....
