1. Experimental evaluation on the structural behavior of truss shear connectors in composite steel-concrete beams
Resumo As estruturas mistas apresentam grandes vantagens quanto a aspectos estruturais e construtivos, sendo os conectores de cisalhamento determinantes para a obtenção da interação entre os elementos estruturais e para a distribuição dos esforços na estrutura, aproveitando-se de forma efetiva da potencialidade de cada material constituinte da estrutu

2. Concrete block structural masonry beam shear design: theoretical and experimental analysis and recommendations to the brazilian standards
Resumo Vigas são submetidas à flexão e cisalhamento, sendo esse último esforço o tema desta pesquisa. O objetivo deste trabalho é analisar especificações para dimensionamento ao esforço cortante de vigas de alvenaria estrutural em blocos de concreto, a partir de extensa avaliação da literatura e de ensaios experimentais aqui relatados. A partir de

3. Experimental Studies on Shear Resistance Performances for the Shear key of H Shape Steel Spatial Grid Roofs
Abstract In this paper, a new type of structure was introduced. The spatial steel grid structure was composed of the top layer, lower layer H-shaped steel ribs and square steel tubes. The shear key is the key part of the structure.Based on the real dimensions of a practical prototype,two sets of full-scale shear key specimens were made, one of which has vert

4. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

5. Sistema integrado com microalgas e wetland construído de fluxo vertical no tratamento de efluentes urbanos
RESUMO O sistema integrado com microalgas (MA) e wetland construído de fluxo vertical (wetland construído pós-microalgas - WCPMA) foi aplicado para a realização de ensaios de tratamento de efluentes no campus da Universidade de Santa Cruz do Sul, no Rio Grande do Sul (UNISC-RS). Águas negras e amarelas foram alimentadas para esse sistema em regime de b

6. Effect of periodization on the physical capacities of basketball players of a military school
Resumo O basquetebol é uma modalidade que impõe cargas fisiológicas importantes aos jogadores durante a competição. O objetivo do estudo foi verificar o efeito do treinamento com periodização ondulatória sobre as capacidades físicas de jovens atletas. Foram avaliadas as capacidades de força explosiva de membros inferiores, resistência aeróbia, fo

7. Recycled gypsum block: development and performance
Resumo O resíduo de gesso ainda é considerado um grave problema econômico e ambiental. Seu volume é alto e sua destinação é muitas vezes inadequada. Visando fornecer uma alternativa mitigatória, esta pesquisa pretende desenvolver blocos que incorporem o resíduo industrial de gesso a partir da logística reversa. Para isso foi realizado um processo d

8. Hankel transformation method for solving the Westergaard problem for point, line and distributed loads on elastic half-space
Abstract The Hankel transformation method was used in this work to determine the normal and shear stress distributions due to point, line and distributed loads applied to the surface of an elastic media. The elastic media considered in this study was assumed to be inextensible in the horizontal directions, and the only non-vanishing displacement component is

9. Reinforced Concrete Beam-Column Inverted Knee Joint Behaviour after Ground Corner Column Loss-Numerical Analysis
Abstract Beam-column joints are critical component in the load path of reinforced concrete (RC) frames, due to their role in transferring loads among different RC frame components. The loss of a ground corner column in a RC frame turns an exterior joint into an inverted knee joint and recent code provisions for exterior joints are not sufficient to knee join

10. Kinematic and electromyographic analysis of school children gait with and without load in the backpack
AbstractIntroduction: Excessive load on the backpacks can lead to musculoskeletal injuries and gait alterations. The objective of this study was to analyze the electromyographic (EMG) activity in association to the kinematic during the stance and balance phases of gait performed with and without the use of the backpack. Methods Twelve volunteers have execut

11. Normal Mode Analysis to a Poroelastic Half-Space Problem under Generalized Thermoelasticity
Abstract The thermo-hydro-mechanical problems associated with a poroelastic half-space soil medium with variable properties under generalized thermoelasticity theory were investigated in this study. By remaining faithful to Biot’s theory of dynamic poroelasticity, we idealized the foundation material as a uniform, fully saturated, poroelastic half-space me

12. Investigating the Influence of Auxiliary Rails on Dynamic Behavior of Railway Transition Zone by a 3D Train-Track Interaction Model
Abstract Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic loads, asymmetric deformations, damaged track components, and consequently, increased maintenance costs. The junction of slab track and ballasted track is one of the existing areas where vertical track stiffness can suddenly change, therefore requiring a tr
