In the article the methodology of comparative analysis of public school teachers’ continuing professional development (CPD) in Great Britain, Canada and the USA has been presented. The main objectives are defined as theoretical analysis of scientific and pedagogical literature, which highlights different aspects of the problem under research; characteristic of the research methodology, used to conduct the comparative analysis. Their major components of the research model (parametric-determining, conceptual and analytical, integrating-analytical and differentiating-analytical, prognostic component) have been defined and specified. Public school teachers’ CPD has been studied by foreign and domestic scientists: political, social, cultural and economic aspects of teachers’ CPD (L. Darling-Hammond, M. Tight); CPD programs (C. Pratt); CPD content (N. Dana Fichtman, M. Rees, A. Ross, S. Zepeda); CPD models, methods and forms (K. Duinlan, P. Grimmet, G. Troia, P. Wong); continuous professional education (Ya. Belmaz, A. Kuzminskyy, O. Kuznyetsova). The research methodology comprises theoretical (comparative-historical, logical, induction and deduction, comparison and compatibility, structural and systematic, analysis and synthesis, general scientific and interdisciplinary forecasting methods), and applied (observations, questioning and interviewing) methods. The research results have been presented.

W artykule przedstawiono wyniki badań ścian skrępowanych (6 modeli) wykonanych z elementów murowych z autoklawizowanego betonu komórkowego (ABK). Wymiary zewnętrzne ścian wynosiły: grubość t = 0,18 m, długość l = 4,43 m, wysokość h = 2,49 m. Ściany badano przy wstępnych naprężeniach ściskających σc = 0,1; 0,75 i 1,0 N/mm2. Skrępowanie wykonano w postaci dwóch zewnętrznych pionowych rdzeni i dwóch poziomych rygli, które zazbrojono zgodnie z wymaganiami PN-EN-1996-1-1. Analizowano morfologię zarysowań ścian i mechanizm zniszczenia elementów.

The paper presents the results of confined (6 walls) made of masonry elements with AAC. Overall dimensions were: thickness t = 0.18 m, length l = 4.43 m and the height of h = 2.43 m. The walls were tested at initial compressive stresses perpendicular to the plane of the bed joints σc = 0,1; 0,75; and 1,0 N/mm2. In the confined models two external vertical cores and two horizontal beams were made, which were reinforced in accordance with the requirements of PN-EN-1996-1-1. The morphology of cracking and the mechanism of destruction were analyzed.
