The pursuit of human being in “upward” architecture goes back to establishment of the gothic church, experiences development of the Chicago School and finally realizes popularization of the international style. Nowadays, the skyscraper has achieved an incredible height, and the techniques of architectural design are diversified just like a hundred flowers in bloom. Nevertheless, the design philosophy of conformity of interior and exterior and unity of form and spirit established by the predecessors at first is still worthy of inheritance. © (2014) Trans Tech Publications, Switzerland.

Ice load is one of the most dangerous factors which threaten the health of offshore structures in cold area. The ice-loading model experiment is an effective method to identify the ice load and to evaluate its influence towards structures. Fiber Bragg grating (FBG) with advantages of reliability, durability and high accuracy, has become one of the most popular sensing element for structural health monitoring and intelligent materials system. In this paper, a novel FBG ice force sensor is presented and applied in the tests of ice loading on bridge pier model. Its sensing property is theoretically analyzed and calibration experiments are conducted. The research results demonstrate that the FBG-based ice force sensor has advantages of small size, high precision and low influence on the structure, showing great prospect for measurement of ice force in model test. © 2011 Published by Elsevier Ltd.

In the present paper, a basic shape determination problem of cable frames is put forward and discussed. At first in the case of no self-equilibrated internal forces but with external loads, the continuous equilibrium equation of a single planar cable frame is given out on the basis of the balance of nodal forces. Then, this equation is extended to the case of exiting self-internal forces but without external loads. In the case of there are no self-internal forces within a cable frame, It will be necessary to assume a functional as the total strain energy of the upper and lower chord of a planar cable frame, the shape determination problem of cable frames will be a calculus of a variational problem with fixed boundary conditions and non-integral constraints. Then on the basis of Euler's equation group the solution of this constrained calculus of variation can be derived out. Hopefully the work in the present paper could be helpful for practicing engineers and researchers.

The Shenzhen VANKE Center included both the required ground clearance to the first floor of 10-15 m as well as unsupported spans in excess of 50 m. The concept of building on cable-stayed bridges was finally selected. Long-span buildings are usually associated with special purpose structures, and the type of structural systems that consequently have evolved can be viewed as an extension of the concepts used in the construction of domes and arches. A reinforced concrete floor system at all levels also was not a desirable option because of the anticipated difficulty in controlling cracking, especially on the first floor. Hence, a composite frame system with steel beams on the first floor to control cracking and wide RC beams on the upper floors provided a better option to coordinate structural deformations. The horizontal length of the building is over 500 m with different heights in different segments. Furthermore, the basement is a little shorter than the aboveground structure.

Due to the existence of underground subway, basement cannot be designed for the tall building above the subway, thus shallow foundation is adopted. This paper performs some discussions on this issue. If the depth of foundation exceeds the limit value specified by the item 5.13 of 'Code for design of building foundation'and item 12.1.7 of 'Technical specification for concrete structures of tall building', this paper suggests that the code requirements can be released by analyzing the overturning of tall building under the wind or seismic loads, the foundation's zero-stress area, the pile's vertical and level bearing capacity and the pile's capacity to resist pulling force due to major earthquakes function and adopting some reasonable measures strengthen the foundation's stiffness. This study can provide references to similar projects.

A new through-beam connection system for a concrete filled steel tube column to RC beam is proposed. In this connection, there are openings on the steel tube while the reinforced concrete beams are continuous in the joint zone. The moment and shear force at the beam ends can be transferred to column by continuous rebar and concrete. The weakening of the axial load and shear bearing capacity due to the opening of the steel tube can be compensated by strengthening steel tube at joint zone. Using this connection, construction of the joint can be made more convenient since welding and hole drilling in situ can be avoided. Axial compression and reversed cyclic loading tests on specimens were carried out to evaluate performance of the new beam-column connection. Load-deflection performance, typical failure modes, stress and strain distributions, and the energy dissipation capacity were obtained. The experimental results showed that the new connection have good bearing capacity, superior ductility and energy dissipation capacity by effectively strengthen the steel tube at joint zone. According to the test and analysis results, some suggestions were proposed to design method of this new connection. Copyright © 2014 Techno-Press, Ltd.

The most common analysis method of complex highrise buildings is the response spectrum analysis, elastic time history analysis, pushover analysis and etc. For the analysis of those highrise buildings whose height is higher than 200 meters, their natural periods are longer than 4 seconds, the dynamic nonlinear analysis would be more accurate. In this paper, the dynamic nonlinear analysis was executed by using the Perform-3D program. Through the analysis, the structural dynamic response and plastic stages due to a rare earthquake were obtained, which also satisfied the seismic performance objectives of Chinese design code.

Taking Harbin west railway station as the researching object, the wind load distribution on a rigid model was measured simultaneously in a wind tunnel firstly. The fluctuating wind pressure field was reconstructed based on the synchronous multi-pressure scanning technique of wind tunnel tests and the proper orthogonal decomposition (POD) technique in order to eliminate the mismatch of the measurement points in wind tunnel tests and the structural nodes. Then the finite element models of the upper steel structure and the whole structure were constructed respectively and the influence of lower RC structure on wind-induced vibration was investigated. The study finds out that the stiffness degradation due to the neglection of the lower RC structure will result in an underestimation of the wind-induced response. At last, equivalent static wind loads (ESWL) for multi-objective were estimated for structural design. A new method was introduced to obtain ESWL that reproduce all largest load effects at the same time. The largest load effects obtained by the ESWL show good agreement with those directly estimated by time domain response analysis.

Beam-String Structures and suspen-domes are two typical hybrid spatial structures. Nowadays they are popularly adopted for large-span roof systems such as air terminals, convention & exhibition centers and sports arenas. This paper discusses the shape determination of hybrid spatial structures, and then proposes an efficient numerical algorithm to implement it. On the basis of the general inverse equilibrium matrix of the lower cable-bar system and the dynamic relaxation method, this numerical algorithm is programmed using VC++ 6.0 and validated through some numerical examples. Hopefully the work presented in this paper could benefit the further research work and engineering practice on hybrid spatial structures.
