NingBo-Liansheng International Commercial Plaza is a twin towers with high-connection. It is a complex tall building. The frame-shear wall structure system is used. The connection body is in 21 and 22 layers. The connection system is strong connection and the two storey steel trusses are used. The north and South towers are placed by certain angle, and it designed for the adjustment of plane wi...

We study the problem of Michell trusses when the system of applied equilibrated forces is a vector measure with compact support. We introduce a class of stress tensors which can be written as a superposition of rank-one tensors carried by curves (lines of principal strains). Optimality conditions are given for such families showing in particular that optimal stress tensors are carried by mutual...

Evolution Strategies (ES) are a class of Evolutionary Algorithms based on Gaussian mutation and deterministic selection. Gaussian mutation captures pair-wise dependencies between the variables through a covariance matrix. Covariance Matrix Adaptation (CMA) is a method to update this covariance matrix. In this paper, the CMA-ES, which has found many applications in solving continuous optimizatio...

This report documents the results of a survey of current practices and technology for the evaluation and rehabilitation of historic metal truss bridges. It is intended to aid engineers in identifying solutions to typical problems found in older metal truss bridges, including inadequate strength, damage, deterioration, and inadequate height and width. This study included a literature search as w...

Understanding and controlling spreading processes in networks is an important topic with many diverse applications, including information dissemination, disease propagation and viral marketing. It is of crucial importance to identify which entities act as influential spreaders that can propagate information to a large portion of the network, in order to ensure efficient information diffusion, o...

The Genoese roof structures are characterized by the originality of their construction and technological solutions compared to other cultural geographical areas, including neighbouring ones, and, in particular, unique connection with underlying wall structures, thrusting nature scarce or non-existent presence trusses. From second half 16th century, roofs large spaces such as churches assembly h...
