An adaptive truss is a truss structural system equipped with functional truss members, such as length-adjustable members, shape memory alloy (SMA) members, spring-dashpot members, and so on. This is a representative example of so-called adaptive structure. In this study, we deal with the dynamic simulation of various types of adaptive trusses. The geometrical relation is given in a universal form applicable to all planar and spatial trusses. We develop descriptions of dynamic behavior of various types of functional truss members and give a general form of the descriptions. The equation of motion is formulated based on the geometrical relation and the description of member characteristics. Dynamics simulation procedure based on the Newmark Beta method is also developed. Dynamic behaviors of several types of adaptive trusses are simulated. The feasibility of the proposed dynamics calculation is confirmed; some characteristic dynamic behaviors of adaptive trusses are demonstrated.

В статье доказана порочность переустройства только одной структурной системы (реструктуризации), так как это чревато поломками элементов, звеньев и блоков, сомой системы кожной службы. Допустимо лишь незначительная адаптация к конкретным условиям больниц, где это будет внедряться. Сформулированы понятия конечного результата работы врачей и структурных подразделений медицинских стационаров в современных условиях общественно-политической формации. Описаны преимущества реконструкции комплекса систем судебно-медицинской экспертизы как экспериментальной службы для кожного отделения городской многопрофильной больницы и работы самого кожного отделения. Описана форма структурного построения судебно-медицинской и кожной служб. По аналоги с экспертным учреждением ожидаются аналогичные изменение конечного результата в кожном подразделении многопрофильного стационара The article proves the viciousness of the reorganization of only one structural system (restructuring), since this is fraught with breakdowns of elements, links and blocks, the soma of the skin service system. Only slight adaptation to the specific conditions of the hospitals where it will be implemented is acceptable. The concepts of the final result of the work of doctors and structural units of medical hospitals in the modern conditions of the socio-political formation are formulated. The advantages of reconstruction of a complex of forensic medical examination systems as an experimental service for the skin department of a city multidisciplinary hospital and the work of the skin department itself are described. The form of structural structure of forensic and skin services is described. By analogy with an expert institution, a similar change in the final result is expected in the skin department of a multidisciplinary hospital

Horizontal loads such as earthquake and wind are considered dominant loads for the design of tall buildings. One of the most efficient structural systems in this regard is the tube structural system. Even though such systems have a high resistance when it comes to horizontal loads, the shear lag effect that is characterized by an incomplete and uneven activation of vertical elements may cause a series of problems such as the deformation of internal panels and secondary structural elements, which cumulatively grow with the height of the building. In this paper, the shear lag effect in a typical tube structure will be observed and analyzed on a series of different numerical models. A parametric analysis will be conducted with a great number of variations in the structural elements and building layout, for the purpose of giving recommendations for an optimal design of a tube structural system.
