Recomendaciones para el análisis de muros de sótano, sometidos a cargas verticales originadas por pilares de fachada

in projects pertaining to basement walls in buildings, justification of only vertical batter and soffit reinforcements is quite habitual, the same by way of elastic calculation of the efforts generated by the soil's thrust action, external overloads and exterior water thrust to the building. analysis of the walls along their longitudinal plane, collecting loads at coronation and transmitting these to the soil through wall foundations, is hardly covered in technical literature and as a consequence the same does not appear in the calculation annexes of the projects. this is likewise the case with the local support effect of the pillars over the walls and interaction in accordance to the rigidity with regards to the different elements intervening in the problem, as is the case with the superstructure, basement wall, foundations and terrain, effects that are likewise not taken specifically into consideration in the calculations. all these analysis may give rise to supplementary reinforcement that is not contemplated in the projects, resulting in retraction and temperature reinforcement that is arranged for other reasons actually being in charge of absorbing these efforts that are not conventionally analysed in the projects. thus this investigation has been put forward with the idea of covering the void that exists in the design of basement walls, the same constituting mr. alvaro pe？a fritz' doctoral thesis (14), in which professor jose calavera ruiz has been his director and mr. manuel llorens alcon has acted as the counsellor, analysing the sensitivity of said walls in view of variation in the respective rigidity of the superstructure, basement wall and terrain, attempting to obtain practical tables and recommendations in order to determine the supplementary reinforcements that are necessary for these concepts.
