Main Component

In high-rise concrete structures, the elevator or stairs which located in the middle of the building are always put into the RC core walls. It not only meets the requirements of the function of usage, but also makes the core walls bear most of the lateral force and becomes the main component in the whole structure that resists the lateral force. Therefore, the seismic performance of RC core walls is of great concern to engineering. At present, there is little experimental study on measures of improving the seismic performance of RC core walls. In this paper, firstly, a new type of construction measure is put forward to improve its seismic performance. Secondly, through the experimental study on one 1/6 scale core walls with concealed bracings and one 1/6 scale normal core walls under the low cyclic loading, the effect of concealed bracings on bearing capacity, stiffness, ductility, hysteresis, failure phenomena and energy dissipation of concealed bracings are discussed. The experiment shows that the seismic performance of RC core walls with concealed bracings is improved remarkably.

The lateral load-resisting system of high-rise buildings in regions of low and moderate seismicity and strong wind such as the typhoon in the Korean peninsula considers the wind load as the governed lateral force so that the practical structural engineer tends to skip the evaluation against the seismic load. This study is to investigate wind-designed steel diagrid buildings located in these regions and check the possibility of the elastic design of them out. To this end, first, the diagrid high-rise buildings were designed to satisfy the wind serviceability criteria specified in KBC 2016. Then, the response spectrum analyses were performed under various slenderness ratio and wind exposures. The analyses demonstrated the good seismic performance of these wind-designed diagrid high-rise buildings because of the significant over-strength induced by the lateral load-resisting system of high-rise buildings. Also, the analysis results showed that the elastic seismic design process of some diagrid high-rise buildings may be accepted based on slenderness ratios in all wind exposures.

An experimental study was carried out to examine the material and structural properties of a new type of structural insulated panel (SIP) comprising the plywood board as facial panels and the Styrofoam as the core material. Material properties were characterized by subjecting specimens to bending, compression, tension and double shear tests. SIP specimens, both in small-scale and prototype sizes, were tested under bending, racking and axial loads respectively. This paper will report these tests and the obtained results.

Shear wall is the main component that resists the lateral force for high-rise buildings. With the rapid development of high-rise buildings, especially the super high-rise buildings, requirements for seismic performance of shear walls have become more sophisticated. This introduction summarizes the commonly used in embedded development and existing problems of steel plate shear wall, which are stiffened steel plate shear wall, non-stiffened steel plate shear wall, composite steel plate shear wall, preventing buckling of steel plate shear wall and low yield point steel plate shear wall.

In order to improve the seismic performance of common concrete shear wall with concealed bracings, fiber reinforced polymer modified concrete instead of ordinary concrete was applied to the shear wall as described in this paper. In this paper, the experimental study on the seismic performance of two different types of shear walls under cyclic loading was carried out, and also the failure characteristics, bearing capacity, ductility, hysteretic curve, stiffness attenuation and energy dissipation performance of the proposed shear wall were analyzed systematically. The test results show that the seismic performance of fiber-reinforced polymer modified concrete shear wall is significantly improved because its the damping ratio, deformation capacity and energy dissipation capacity are greatly improved compared with ordinary concrete shear wall with concealed bracings, which ensures its better stiffness stability in the later stage.

Beam Plastic Hinge

This paper presents a new-type of fabricated beam-column connections with end plates. The joint details are as follows: the concrete beams are connected to column by end plates and six high strength long bolts passing through the core area. In addition, in order to increase the stiffness and shear strength, stirrups are replaced by the steel plate hoop in the core zone. To examine the fail behavior of the fabricated beam-column connection specimens, a quasi-static test is conducted for nine full-scale models to obtain the hysteresis curves, skeleton curves, ductility, energy dissipation capacity, and other seismic indicators. The experimental results show that all specimens failed in bending in a malleable way with a beam plastic hinge and the hysteresis curves are excellently plump for the end plate connections. From the seismic indexes, the fabricated connection specimens exhibit better seismic performance, which can provide reference for the application of prefabricated frame structure in the earthquake area.

Modular Structures

The construction industry has tried out a variety of trends in its field to bring out innovative, economic, efficient and sustainable infrastructure to meet the growing demand. One such development is the off-site manufactured modular steel buildings. The practice reduces the construction period as well as reduces wastage of resources. It was extensively used for low rise structures earlier, but due to increasing urban construction demand the practice is preferred nowadays in high rise structures too. For the high rise structures the lateral stability needed to be well looked into as there may arise a mass irregularity, structural irregularity, discontinuity etc. Psychological acceptance of such construction practice by the public is also not assured as they are not well aware of the advantages and use of the practice. And hence there is a need to conduct detailed and thorough investigation on its contradiction part to seismic performance. The modular construction consists of different structural systems and load transferring mechanisms. The integration of many materials and elements to modular structures are also discussed in various papers. But regarding lateral force resistance of its structural and non-structural components only limited research is conducted. Further research is required. The aim of the study is to provide a collective critical review on individual units or components of the structural system and their effects contributing to seismic resistance.

Cyclic Loading Tests

Low-cyclic loading tests were carried on brick walls bonded with mud reinforced by three methods: packing belts, one-side steel-meshed cement mortar, and double-side steel-meshed cement mortar. The failure modes, hysteresis curves of the load-displacement, skeleton curves, and ductility were obtained. The results showed that the bearing capacity of the brick walls bonded with mud reinforced by the abovementioned three methods had been increased to 1.4, 1.7, and 2.2 times as much as that of the unreinforced brick walls, respectively, and the ductility of the reinforced brick walls had been increased to 4.7, 2.1 and 2.2 times, respectively. The integrity and ductility of the reinforced brick walls were effectively improved in different degrees. The experimental results provided specific seismic strengthening techniques for the farmhouses built with brick walls bonded with mud.
