Philosophical concepts, biased toward structural design in seismic regions, are offered. Certain misconceptions in the aims, planning and execution of structural design are sketched. Apparent diverging professional interests, motivating on the one hand young academics dedicated to pursuing challenges in research, and on the other hand those of experienced practitioners, are contrasted. A plea is made to use in seismic design rationality and simplicity in application. The primary aim in the art of structural design should be to impart to the system specific properties that will make the seismic response of our buildings extremely tolerant with respect to earthquake-induced demands, which presently we can predict only with considerable crudeness. A postulated rational and deterministic, yet simple, design strategy should be implemented with equal dedication to high-quality construction. This part of the creative effort is likely to result in properties of the finished product, our buildings, which earthquakes will also recognize and respect. An appeal is made to all those committed to earthquake engineering to engage in active and generous support of technology transfer in an attempt to alleviate the overwhelming and immediate needs of societies in developing countries.

Dongjiang Lichuan Bridge in Dongguan City is a curved tower curved beam cable-stayed bridge with a main span of 138m and no back cable. The main pier cap is located on the bank slope of Dongguan Waterway on one side of Nandi Road. The cushion cap is dumbbell type, and the left and right cushion caps are connected by tie beams. In most areas, the top of rock stratum is above the bottom of bearing platform. The rock stratum within the buried depth of bearing platform is moderately to strongly weathered argillaceous siltstone. The geological conditions are complex and the construction is difficult. In line with the principles of speeding up the construction process and improving economic benefits, comprehensive analysis and weighing advantages and disadvantages, the main pier cap adopts a composite cofferdam of filling soil to build an island and combining bored pile rows and steel sheet piles. The construction task of bearing platform of main pier has been completed with high quality. Compared with other cushion cap construction methods, this construction method has the advantages of fast construction, high quality, simple safety, energy saving and environmental protection. This paper briefly introduces the design scheme of composite cofferdam, expounds in detail the operation steps of steel sheet pile construction and the problems needing attention in construction, and provides good reference experience for similar pile cap construction.

Concrete filled steel tube is widely used in super high-rise steel structure, but there are many problem in the construction of concrete filled steel tube. With the construction of Wanxin building as an example, this paper described the selection of the construction program, and analyzed the disadvantages in construction such as the difficulties of concrete pumping and the problems of pipe blockage, pipe explosion and concrete curing during the process of construction. Based on structural characteristics and construction difficulties, the key technique of steel tube concrete construction are introduced in detail. It can provide significant reference and guide for super high-rise building construction.

Large-span hybrid structure of suspendome with stacked arch is applied into steel roof of Chiping Gymnasium. The construction of this new type structure system is difficult according to structure characteristics such as its large-span stacked arch, high installation altitude, lattice shell installation, prestressed cable tension, and tight construction period. Temporary support frame, segment lifting and high altitude splicing construction method is adopted to install the stacked arch, and total support, high-altitude spread operation method is used to install lattice dome. A spatial structural analysis is conducted on the supporting system, and the finite element software is adopted to simulate and analyze the installation process of the steel structure roof system. At the same time, stress and deformation of the roof structure are monitored by precise instruments and equipments. As the result, construction safety and quality are guaranteed.
