This paper is the first of a series of works, which the authors have devoted to the analysis of experimental data available in the literature on the influence of various factors on the strength of reinforced concrete monolithic walls of civil buildings. Among them the most significant ones were identified: the ratio of height to wall width, the ratio of height to wall thickness, the class of concrete and the class of reinforcement, the reinforcement scheme and the loading scheme, etc. The most important factors were identified. It is established that the scientists of the past and present in their works, due to the complexity and costliness of experiments, considered a limited small number of factors in a separate study - 1...3, often without taking into account their mutual influence. There is no theoretical interpretation of the results obtained in these works, and no scientific publications summarising the accumulated experimental material have been found. This paper and our subsequent publications are an attempt to eliminate this gap. In the present paper, a classification of all factors is given and the joint action of factor No. 1, which takes into account the H/B aspect ratios, and factor 15c, which takes into account the joint action of vertical and horizontal loads, is considered. The results of this analysis will allow us to make the next step towards the improvement of the methodology for calculating the strength of monolithic reinforced concrete walls, which will take into account the different types of influencing factors as much as possible.
