    In Ecuador, progress has been made in new methods and alternatives for structural design. In this research, two analyses have been generated: one with square profile columns and beams, and another with IPS profiles, following the current Ecuadorian Construction Regulations. The purpose is to examine the contribution of composite columns in moment-resistant frames and compare their advantages with other types of elements, based on the theory investigated. The present study is experimental, since through a mathematical model using specialized software in structural analysis, structural characteristics for the design were found, including the dimensions of the structural elements and the amount of steel used. The objective is to obtain results that allowed the structural behavior of the building to be evaluated and generating an economic analysis. Finally, through a linear analysis, it was observed that the calculated drifts are satisfactory in both cases, being lower than the permissible limit of floor drifts established by the NEC regulations of 0.02. For the IPS profile structure, the drifts were 0.0032 in the X direction and 0.0039 in the Y direction, while for the square profiles they were 0.0079 in the X direction and 0.0086 in the Y direction. Indicating that both structures meet the requirements of the regulations in terms of drifts, but in terms of structural performance the IPS profiles have a better performance, the square profiles having a hollow geometry, this is a lower cost option, therefore the most economically optimal decision will fall on the designer.

    The problem with this project was the handling and transport of tyres in the area, due to the fact that the stacking of these objects is carried out manually, causing musculoskeletal efforts in the operators and a prolonged execution time, slowing down the productivity of the assembly plant. The technical work was developed through the collection of information with the help of the operators in the corresponding area to understand the process of stacking and transporting the tyres with a range of 75 lifts during the eight hours of daily work. Subsequently, the pneumatic design was implemented to a lifting mechanism whose zero gravity type operation improves the ergonomics of this process and speeds up its execution, additionally it meets the transport needs proposed within the company; and finally, the structural design of the bridge crane was developed, verifying the results in accordance with the CMAA-74 and AISC Design Guide 7 standards. The structure was complemented with the mechanism for its execution as a whole to allow its free movement through the work area. At the end of the work, it was found that the time of stacking and transport of tyres was reduced compared to the initial state of the project, which improves productivity in the area of assembly of the company CIAUTO CÍA. LTDA. Likewise, the improvement in ergonomics that is produced thanks to the structure that includes the pneumatic mechanism, benefits the occupational health of each of the operators.
