“…In China, dual systems consisting of steel perimeter frames and central RC core walls are extensively used in high-rise and super high-rise buildings such as the LG Twin Towers shown in Figure 4 and the Fortune Financial Centre shown in Figure 5. The increase in number of such mixed-material buildings prompted several studies including connection tests, numerical analyses and small-scale (1:20) shake table tests [4][5][6][7]15]. There is a consensus that even with major wall damage at lower storeys, the dual concrete wall-steel frame system demonstrated good seismic capacity and deformation capacity in all buildings, provided the connections between core walls and surrounding elements were adequately detailed.…”

Around New Zealand there has been an increasing trend of ‘hybrid’ multi-storey buildings that combine reinforced concrete walls with structural steel framing systems. This study aims to characterise and understand this type of building, focusing on buildings constructed in Auckland and Christchurch from 2014 onwards. Drawings from a total of 50 buildings were reviewed, and their structural features were documented, including building use, building height, lateral load resisting system, ductility, wall configuration, wall construction method, steel framing system and suspended floor system. Meetings with structural engineers were conducted to validate the review findings and to further understand design principles and decisions that lead to these outcomes. A typology comprising five building types with distinct lateral load-resisting systems was proposed based on the building review. Results showed regional differences between Auckland and Christchurch, owing to building use and seismic hazard in the respective cities. Auckland buildings surveyed tended to be residential buildings five storeys or higher made of precast walls connected with steel beams. Christchurch buildings, on the other hand, were primarily commercial buildings three to seven storeys high with dual frame-wall systems. Structural connections between steel frames and concrete walls were also documented, showing that bolted connections with headed stud embedment were most common. The results can be used to identify critical aspects of these mixed structural systems for further investigation and to develop archetype building designs that can be used for modelling and testing.

“…Third, it saves costly alloying elements by satisfying the mechanical properties through control of microstructure and alloy chemistry. 7) In recent years, controlled cooling technology for seamless pipe has been investigated in Baoshan Iron & steel Co. Ltd., which remarkably improves the strength and reduces the cost when residual deformation and residual heat had been used and costly alloying elements had been saved.…”

Development and application of resin capsules in Chinese coal mines were introduced in this paper, including the category, feature, applicability and basic parameters. The paper pointed out that unsaturated polyester resin capsules were the most widely used in Chinese coal mines. A kind of newly-developed low-viscosity resin capsule was applied to industrial test in Fengshuigou Colliery, and the results showed that the high pre-stress and intensive bolting system could effectively control the violent displacements of the surrounding rock, and it provided an effective approach for the support of soft rock roadway. Finally the future developments of resin capsules were prospected.
