Tóm tắt:

Từ năm 2018, cơ quan quản lý nhà nước của Việt Nam đã đề ra kế hoạch chuẩn bị cho một hệ thống mới về các tiêu chuẩn thiết kế và xây dựng, trong đó các tiêu chuẩn châu Âu (Eurocodes) gần đây đã được cân nhắc áp dụng một cách hệ thống và từng bước trong khoảng từ năm 2022 đến năm 2030. Định hướng này đã thu hút được sự quan tâm trong nhiều đề tài nghiên cứu của các nhà khoa học Việt Nam, trong đó có lĩnh vực thiết kế kết cấu bê tông cốt thép (BTCT) theo tiêu chuẩn châu Âu. Bài báo này giới thiệu một số đề tài được triển khai trong quá trình chuẩn bị cho việc áp dụng toàn diện tiêu chuẩn châu Âu cho kết cấu BTCT tại Việt Nam trong thời gian tới khi thích hợp, đặc biệt khi thế hệ thứ hai của Eurocodes dự kiến sẽ được ban hành trong những năm sắp tới.
