In this article, a Python-programmed advanced design paradigm is firstly introduced to topology and size optimization of the X-bracing system nonlinear inelastic space steel frames. For that purpose, an analysis method considering both geometric material nonlinearities utilized as effective finite element (FEA) solver. which, members are modeled by truss elements, while beam column simulated be...

This paper proposed a novel supporting and retaining structure used to high-steep building slope reinforcement. It combined with an anti-sliding pile inclined column, which is as fulcrum on the upper part of pile. The mechanical characteristics are studied firstly by two methods numerical methods, respectively. Result shows that axial force will be evenly distributed along column body it provid...

In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for one-story single-span PCRF. The PCRF studied in this paper has connecting interfaces set at column feet and inner faces beam–column joints, allowing columns be uplifted with accompanying separation interface rotation beam around interface. tend...

Distillation columns are complex processes for modeling and controlling. These columns are significant parts of most chemical industries for separation of components. Control of this process is essential for achieving certain purity for products with a minimum cost. However, nonlinearities, multivariable interaction, non-stationary behavior and severity of disturbances inside the column made th...

Dieser Artikel beschreibt die Verwendung von User Stories für die Beschreibung von Anforderungen aus Sicht des e-Learning im Kontext der Einführung eines integrierten Campusmanagementsystems. Die User Stories bilden die Grundlage für die Kommunikation zwischen den Akteuren des e-Learning und den technischen Entwicklern des Campusmanagementsystems.

In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...

Branching story games have gained popularity for creating unique playing experiences by adapting story content in response to user actions. Research in interactive narrative (IN) uses automated planning to generate story plans for a given story problem. However, a story planner can generate multiple story plan solutions, all of which equally-satisfy the story problem definition but contain diff...

A simplified fracture-mechanics-based model of compression failure of centrically or eccentrically loaded quasi-brittle columns is presented and the size effect on the nominal strength of a column is predicted. Failure is modeled as propagation of a band of axial splitting cracks in a direction orthogonal or inclined with respect to the column axis. The maximum load is calculated from the condi...
