This paper presents the innovative use of hot-rolled thickness-tapered mill products, longitudinally profiled (LP) plates, for the seismic performance of bridge bents of single and portal framed piers. The study involves the inelastic cyclic testing and numerical analysis of tested beam-columns and portal frames in order to evaluate the effects of tapering ratios of LP plates, penetration of yielding, and number of locally buckled panels on their structural ductility. A structural design method is proposed for the portal frames having LP panels under cyclic loadings.

High Rise

<p>With the continuous development and progress of society, the structure of high-rise buildings has been paid more and more attention by the engineering community. However, the existing high- rise structure design methods often have a lot of redundancy and have a lot of room for optimization. Most of the existing seismic design methods of high-rise structures are based on engineering experience and manual iterative methods, so that the efficiency of design can not meet the needs of the society. if the method of design automation is adopted, the workload of designers can be greatly reduced and the efficiency of structural design can be improved. Based on the digital modeling theory, this paper proposes a MAD automatic design algorithm, in which the designer provides the initial design of the structure, and the algorithm carries out the modeling, analysis, optimization and design of each stage of the structure, and finally obtains the optimal structure. The structural design module of this algorithm starts from the component level, when the component constraint design meets the limit requirements of the specification, it enters and completes the component constraint design and the global constraint design of the structure in turn. In this paper, taking a ten-story braced steel frame high-rise structure as an example, the optimal design is carried out, and its seismic performance is analyzed. the results show that the MAD automatic design algorithm can distribute the materials to each part reasonably, which can significantly improve the seismic performance of the structure and realize the effective seismic design.</p>

Abstract The rise of offshore marginal field development and low-cost CAPEX has given an impetus to O&G operators to challenge the common structural platform design especially for wellhead platform type. Demand to reduce the platform weight has been observed for the past 20 years. Typically, the challenge to meet this demand will be tremendous once the water depth exceed 50m. This paper will elaborate on how using an engineered design approach was implemented to obtain fast track onshore fabrication and offshore installation and meet the operator demand for minimal structural concept.

In combination with a industrial plant cantilever structure need be increased for meeting the technological requirements，the three kinds of structural design schemes of cantilever are considered, that is the scheme hanging on steel frame of the plant, prestressed steel frame scheme and steel truss scheme. Three kinds of structural form and materials selection are introduced. By finite element software ANSYS three kinds of schemes are analyzed, carrying capacity and deflection of members under load are acquired, by Comparison steel truss scheme is adopted. Carrying capacity and deflection of structure not only meet requirements, but also the construction is easy. This paper provides reference for resolving similar cantileve r problems in engineering.
