Asphalt concrete pavement often appears damaged such as rutting, fatigue crack, potholes, etc. at high air temperature, heavy rain in long time, or at locations with high traffic, large horizontal force, and poor-quality construction sites. T This paper presents an evaluation of shear bond strength of double-layer asphalt samples fabricated by shear test device with normal pressure.

In this study, a comprehensive database of 146 URM walls was compiled from 26 research groups and employed to evaluate the accuracy of established guidelines, including ASCE 41-17, NZSEE, Eurocode 6, and GB50003. The comparative analysis showed that ASCE 41-17 provided the most accurate predictions with acceptable safety levels, while NZSEE produced more conservative estimates and excelled in predicting diagonal shear failure modes.

The purpose of this research is to analyse the available design equations and present the applicability of these equations for their use in the design of beams made of higher concrete strengths. In the present program concrete having compressive strength of 50MPa or more is considered as high strength concrete. Analytical investigation on HSC beams is made under four different aspects namely flexure, ductility, deflection and shear.

Steel fiber reinforced concrete (SFRC) is a multiple-composite material developed during the early 1970s. In SFRC, short steel fibers are randomly distributed in concrete. Steel fibers can prevent the development of micro-cracks inside the concrete and reduce the expansion and development of the macro-cracks, thus enhance mechanical performance of SFRC. However, there is lack of studies on the influence of flowability of fresh SFRC on the steel fiber distribution patterns and mechanical properties of hardened SFRC.

In-plane strength and constitutive properties of composite materials is known as crucial problems. Although, several studies have been made for obtaining the in-plane mode II properties, the common test fixtures are blind in confrontation of shear zone. Furthermore, toughening mechanisms and consequently mode II fracture toughness cannot be evaluated, precisely.

Chấn thương đụng dập (blunt trauma) là do sự kết hợp của các lực ép (crushing), kéo căng (stretching), và cắt xé (shearing). Độ lớn của những lực này tỷ lệ với khối lượng của các vật, tần số thay đổi vận tốc (gia tốc và giảm tốc), hướng va chạm, và khả năng đàn hồi của các mô. Thương tổn xảy ra khi tổng số của những lực này vượt quá sức cố kết (cohesive strength) và tính di động của các mô và cơ quan liên hệ. Sự truyền năng lượng cao vào bụng gây nên một...
