Estudio analítico de placas base adaptadas con la guía de diseño 1 del AISC, considerando columnas tubulares huecas para el caso de un edificio de acero estructural de nueve niveles
(2022-03)
The issues that arise from the connections application without specific support are
mainly focused on security. In steel structures, carrying out a correct design of the connections
at the base of the column is essential, ...
LDPE Production in Tubular Reactors: Comprehensive Model for the Prediction of the Joint Molecular Weight-Short (Long) Chain Branching Distributions
(American Chemical Society, 2019-03)
Good control on molecular properties, and as a consequence on end-use properties, is very important for low-density polyethylene (LDPE) manufacturers. However, the connection between the architecture of polymer chains and ...
Tilt-critical algebras of tame type
(TAYLOR & FRANCIS INC, 2008)
Let A be a finite dimensional k-algebra over an algebraically closed field. Assume A=kQ/I where Q is a quiver without oriented cycles. We say that A is tilt-critical if it is not tilted but every proper convex subcategory ...
Estudo teórico-experimental do comportamento de barras compostas comprimidas formadas por perfis tubulares circulares concêntricos laminados de aço
(Universidade Federal de Minas GeraisUFMG, 2018-04-05)
This paper presents a theoretical-experimental study on the behavior of built-up members axially compressed formed by concentric hot rolled circular hollow sections. The use of these bars is an innovative solution for ...
Diseño de conexiones sísmicas implementando diafragmas en columnas de acero tipo cajón conectadas a vigas i para edificios ubicados en suelos blandos de Guayaquil
(Universidad de Guayaquil - Facultad de Ciencias Matemáticas y Físicas - Carrera Ing. Civil, 2023-03)
Cuando se busca una conexión estructural segura y costeable la innovación se vuelve limitada, las conexiones especiales de diafragma externo y diafragma interno con RBS han demostrado su efectividad en numerosos ensayos, ...
Calificación de una conexión rígida de una viga i y una columna tubular rellena de concreto bajo la acción de cargas dinámicas
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2009)
En el desarrollo de proyectos de ingeniería estructural que comprometen elementos de acero, cada día se hace más necesaria la posibilidad de emplear en la etapa de diseño conexiones precalificadas que garanticen el adecuado ...
Levantamento de poços tubulares profundos perfurados no município de Concórdia - SC entre os anos de 1981 a 2006
(Universidade Tecnológica Federal do ParanáMedianeira, 2014-04-12)
The present study sought to identify the amount of deep wells drilled in the municipality of Concordia - SC between the years 1981-2006. For this research was a quantitative and involved five companies that performed well ...
Suturable elastomeric tubular grafts with patterned porosity for rapid vascularization of 3D constructs
(2021-07-01)
Vascularization is considered to be one of the key challenges in engineering functional 3D tissues. Engineering suturable vascular grafts containing pores with diameter of several tens of microns in tissue engineered ...
