Dentro de los pasos en el proceso editorial de una revista de carácter científico, se encuentra la evaluación de los documentos remitidos por los autores para su posible publicación, realizado por expertos denominados evaluadores o revisores, encargados de examinar los trabajos en sus diferentes modalidades a fin de emitir un veredicto sobre los mismos. Esta relevante labor permite a las publicaciones mantener su calidad, siguiendo las líneas editoriales garantizando la pertinencia de los contenidos, los métodos empleados y originalidad de los trabajos

This research aims to analyze the elastoplastic behavior of welded connections of square section steel tubes subjected to monotonic loading, by means of the theoretical - experimental comparative analysis of the distortion of the cross section geometry of the elements of the beam - column joint. For the experimental tests it was necessary to build a rigid support frame designed with STAAD software. Pro v8i, of fixing and assembly to the gantries and load application system of the universal machine of the Materials Laboratory of the Faculty of Engineering of the University of Zulia. In every test a progressive load (monotonic load) was applied on the upper connection of the gantry to systematically to measure displacements and distortion of the geometry of the beam jointing elements column of the lower connection. While the theoretical model was performed using the finite element program [4] ANSYS Workbench. The obtained results show that: the welded connection presents a local failure by punching in the column that reduces the theoretical plastic moment capacity of the gantry "Mp" by 46%, scenario of concern for being this capacity used in the design under the theory Design for Load and Resistance Factors (LRFD). The welded connection (node) does not meet the weak beam strong column criterion established by Norma. The column of the welded joint must be reinforced to avoid the formation of the plastic ball joint and a possible mechanism of collapse in the gantry

The architecture, engineering and construction industry has great activity and importance, it moves other areas to satisfy the infrastructure needs of most economic and social activities, such as housing, roads, education, industry and health, among others However, it is one of the industries with the lowest productivity and which seems not to have taken advantage, as do other production sectors in general, of the opportunities offered by some management philosophies to solve complications and difficulties. This article analyzes the most relevant lessons learned from the implementation, both in the previous phases and in the link or relations between them, and in the corporate area of the company, when applying the constructablity in the planning stages, design and acquisitions, guiding the objectives of multidisciplinary teams towards the integration of a housing project built in Barquisimeto, Venezuela. The methodology was used in the integral process of the project, prior to the preliminary project, which led to the continuation of benefits in costs, times and quality of the final product in a pilot project

Barquisimeto, capital of Lara State, Venezuela, has a Local Urban Development Plan approved in August 2003 whose validity was estimated until 2016, which is why the municipal authorities have the responsibility of assuming its updating or the formulation of a new plan that rules the urban planning of the city for the next twenty years. The formulation of the plan is a task in which all the dimensions that make up the development of the city must be considered given the essential multi-sectorial approach, requiring solving some problems in the urban dynamics, as well as some weaknesses of the current instrument. Through this work we propose a set of ideas on key aspects that the new instrument should address, such as: consider international agreements related to the objectives of sustainable development and the new urban agenda, the role of Barquisimeto in the sub-region, the integration of neighborhood areas, the incorporation of Transbarca, the consideration of new employment centers and dynamics, review of zoning, innovation in the provision of equipment and the protection of built heritage, incorporating urban action programs from the perspective of the strategic plans and, finally, the strategy of implementing the macro plan with micro plans. To achieve its purpose, the work identifies information sources and local, national and international experiences that will serve as a reference to the professional team that assumes the challenge of designing the new Local Urban Development Plan
