Experimental investigation of octagonal partially encased composite columns subject to concentric and eccentric loading
Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Analytical Solutions for the Flexural Behavior of Metal Beams Strengthened with Prestressed Unbonded CFRP Plates
Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...
متن کاملFlexural Behavior of Reinforced HPFRCC Beams
High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...
متن کاملBehavior of Castellated I Beams Encased in Concrete
Five methods are introduced for design of castellated I beams encased in concrete. One of the methods, plastic analysis, is thoroughly explained and the relevant equations are developed. Eight castellated I beams encased in concrete are made and tested. The theoretical design methods are all compared with the test results and the safety factor for each method is calculated. The results show tha...
