TL;DR: In this article, the authors conducted quasi-static tests on seismic behavior of two groups of composite shear walls with double steel plates and filled concrete to investigate the structural mechanism and the typical failure modes.
Abstract: Quasi-static tests on seismic behavior of two groups of composite shear walls with double steel plates and filled concrete were conducted to investigate the structural mechanism and the typical failure modes.In the tests,all the specimens illustrated good ductility and energy dissipation ability with stable and full hysteretic curves.The ultimate drifts of all the specimens exceeded the limit value recommended by the current design code,and were also larger than the similar test results provided by other researchers.Batten plates tied the double steel plates can effectively prevent the steel plates from local buckling and enhanced the confining effect on the infill concrete.As a result,the high-strength concrete can be used in seismic shear wall structures and the design requirements of 'high compression,high ductility and small thickness' for shear walls in super high-rise buildings can be fully satisfied.Based on the experimental research,theoretical analysis and numerical simulation were conducted,and the preliminary design recommendations for the application of the composite shear wall with double steel plates and filled concrete were further presented.The research work to be further conducted was finally proposed.From this research,it can be concluded that since the composite shear wall with double steel plates and filled concrete has good ductility,superior energy dissipation ability,and simple details requiring convenient construction methods and avoiding the exposure of concrete cracks,it has wide application prospect in super high-rise buildings.

TL;DR: In this article, the turn-of-the-nut method as a rotation-control method is examined which is different from the torque control method and the theory of different tightening methods are discussed.
Abstract: At present,torque-control and turn-of-the-nut are mostly used as the fastener installation methods to produce a bolt tension in steel structure of civil and traffic constructions The turn-of-the-nut method as a rotation-control method is easily operated and examined which is different from the torque-control method The tightening behavior of a bolt-nutwasher assembly and theory of different tightening methods are discussed in this paper The research studies the tightening processes of M20 and M24 fastener assemblies of 8 8 and 10 9 grade to get the relationship between nut rotation and bolt tension The nut rotations to reach the specified fastener tension from a snug position are finally summarized and the ultimate nut rotational capacity is discussed All the results described above give some installation requirements and recommendations for the turn-of-the-nut method

TL;DR: In this article, the elastic-plastic fiber model has been used to simulate beam and column, and a dynamic integral was carried out from material stress-strain constitutive relation.
Abstract: The elastic-plastic fiber model has been used to simulate beam and column.Dynamic integral was carried out from material stress-strain constitutive relation.Frame rigidity and restoring forces properties were obtained directly.Computational methodology suitable for the fiber model and uniaxial stress-strain relation of reinforcement and concrete are presented.FEM software of ABAQUS was used to calculate the pseudo dynamic cyclic loads on concrete cantilever column and frame,and comparative analysis with test results was done.

TL;DR: In this paper, the fire endurance of timber beams is determined not only by the mid-span displacement, but also by the changing rate of midspan displacement and the effective factors of fire endurance such as load level, cross-section and fire retardant coating, 7 specimens of 2 series were experimentally studied.
Abstract: The fire endurance of timber beams is determined not only by the mid-span displacement,but also by the changing rate of mid-span displacement.To learn the effective factors of fire endurance such as load level,cross-section and fire retardant coating,7 specimens of 2 series were experimentally studied.The results show that,according to mid-span displacement and changing rate of mid-span displacement,the fire endurances of B100P25,B100P37.5 and B100P50 are 23,17,12min respectively,and the fire endurances of B150P50 and B150PC50 are 37 and 48min.The fire endurance of the timber beam exposed to three-side fire has an obvious decrease when the load level increases,has a prominent increase when the corss-section increases,and also has an obvious increase when the fire retardant coating is used.
