Hollow (empty) concrete blocks are commonly used in masonry construction due to their low self-weight, efficient material usage, and favorable thermal performance. The structural response of masonry systems constructed from such blocks is governed not only by the material properties of the blocks themselves, but also by the mechanical behavior ...

در این ویدئوی آموزشی به شبیه سازی بارگذاری فشاری و عرضی بلوک های سیمانی با تماس کوهسیو در نرم افزار آباکوس پرداخته ایم. بلوک های سیمانی به صورت بلوک کامل و نیمه در چهار ردیف در قالب پارت های سالید طراحی شده اند. فضای خالی میانی بلوک ها عایق صدا ...

Refractory concrete materials are widely used in high-temperature structural and industrial applications due to their excellent thermal stability, fire resistance, and durability under extreme environmental conditions. However, conventional refractory concrete exhibits inherent brittleness and limited tensile strength, which can lead to premature cracking and sudden failure under mechanical loading. To ...

Concrete-filled steel tube (CFST) shear walls have been widely applied in high-rise and seismic-resistant structures due to their excellent load-bearing capacity, ductility, and energy dissipation performance. By combining the advantages of steel and concrete, CFST systems effectively delay local buckling of steel tubes while enhancing the compressive strength and confinement ...

Introduction Lightweight sandwich composite structures have gained significant attention in aerospace, automotive, marine, and defense applications due to their high specific strength, excellent energy absorption capacity, and superior impact resistance. Among these, glass fiber–reinforced polymer (GFRP)–metal foam–GFRP composite panels represent a promising class of hybrid sandwich structures that combine the ...

In this example, an SSFRRC beam with a normal concrete outer layer, CFRP composite material, and steel bars as reinforcement is considered. To model the SSFRRC beam, the Concrete Damaged Plasticity model is used for the refractory concrete; the Johnson–Holmquist model is applied to the normal concrete; the Johnson–Cook hardening ...

Interlocking masonry constructed from rubberized concrete represents a sustainable alternative to traditional masonry systems, offering benefits such as reduced material waste, improved deformability, and enhanced energy absorption. The incorporation of recycled rubber into concrete alters its mechanical behavior, introducing nonlinear characteristics that influence the performance of interlocking block assemblies under ...

The dynamic analysis of three-point bending tests on bolted steel splice connections provides vital insight into the structural performance of steel members subjected to impact or rapidly applied loads. Unlike quasi-static loading, dynamic bending introduces strain-rate effects, inertia forces, and potential changes in failure mechanisms that can significantly influence the ...
