The buckling-restrained brace has stable energy dissipation capability. It has been widely used in recent years. This paper uses finite element software ANSYS to do non-linear time history analysis for Center Braced Steel Frame, Eccentrically Braced Steel Frame, Buckling-restrained Braced Steel Frame under the earthquake. The results show that: (1) The peak acceleration, residual displacement and top floor displacement of buckling-restrained braced steel frame is smaller than the other two brace frames, provide support for the structure stability.

Abstract:

Braced frames intended to resist wind and seismic loads traditionally have been analyzed and designed as trusses with all joints modeled as pins, such that only the braces provide lateral force resistance. However, frames with gusset plate connections create a rigid joint zone between frame beams and columns, effectively resulting in moment frame behavior, particularly at larger drift angles when braces have yielded or buckled. Described herein are the force distributions for buckling-restrained braced frames (BRBF) subjected to story drift angles, where the lateral resistance of the frame com

Abstract:

Buckling-restrained braced frames are steadily replacing concentrically braced frames because buckling-restrained brace can yield without buckling when subjected to both tension and compression. Though buckling-restrained brace frames are being widely used as framing structures for construction in high seismicity areas, it is shown that at large strains, a considerable amount of permanent deformation is produced at the support connector between the brace and the frame. This drawback can be overcome by providing recentering capabilities to the braced frame system. By applying the concept of a r

In this paper, a new model named as “brace01” for steel brace is presented on the basis of experimental data on different types of steel struts. This model shows a peasant capability in the structural analysis of Concentrically Braced Frames. A brace is idealized as a pin-ended member with a plastic hinge located at its midspan. This expression of the model is proposed by combining the mechanical properties and the phenomenological characters. The model for steel brace is implemented in an effective way in OpenSees.

Chevron or inverted V‐braced frames are generally preferred because they allow large openings for doors and windows.

This paper reports an investigation into the buckling of frames with braces whose stiffness is insufficient to prevent sway buckling. Formulae are presented to calculate the effective column length for these weakly braced frames. Threshold stiffness values for the braces are obtained which are just enough to make frame buckle in a non-sway mode. After taking the influence of initial imperfection and lateral loads into account the brace threshold stiffness may be used as a rational basis for classifying sway frames and non-sway frames.

A new type of connection has been developed for steel-braced frame systems that allows the brace members to undergo compression buckling in the in-plane direction. In addition to the inherent benefits of in-plane buckling (IPB) braces that help in reducing the extent of damage to the non-structural components, the IPB brace system is also considered to be an efficient way of retrofitting existing seismically deficient structures. The use of the compact and thicker gusset plate prevents the distortion of the free edges and the additional torsional force demand on beams and columns. However, IPB

In concentrically braced frames (CBF), gusset plates as the connected members are subjected to forces not only from brace but also from frame action. When the braced frame is deformed, the beam-column connection will deform, and the deformation of beam-column connection either “open” or “close” as the brace under “compression” or “tension”. Therefore, the design of gusset plate should consider the effect of such frame action, in addition of the brace axial load.

Eccentricity on the braced frames can sometimes not be avoided to facilitate some structural considerations, such as openings. V-type braced frames are among the most widely used bracing types because of their satisfying performance. The present study investigated the effect of eccentricity as 15 cm, and 25 cm on the reinforced concrete braced frames of 80 cm x 100 cm in dimension compared to V-type of Concentric Braced Frame (CBF). Results indicated that a frame with 15 cm of eccentricity has almost similar stress but higher strain compared to the CBF while the frame with 25 cm of eccentricit

Abstract:

Off-center or gate braced frames are a special configuration of inverted V bracing with non-straight diagonal members that are made of two elements connected to the corner of the frame by another member. This arrangement is characterized by an eccentricity of the intercepted bracing as respect to the straightness of the theoretical working length of the diagonal members in chevron configuration. These types of braced frames permit larger openings with significant advantages in terms of architectural functionality. The seismic performance of gate braced frames differs from that of traditional c

This paper presents the results obtained from tests of a new friction damping system, which has been proposed in order to improve the response of steel Moment Resisting Frames (MRF) and Braced Moment Resisting Frames (BMRF) during severe earthquakes. The system consists of a mechanism containing brake lining pads introduced at the intersection of frame cross-braces. Seismic tests of a three storey Friction Damped Braced Frame (FDBF) model were performed on an earthquake simulator table. The experimental results are compared with the findings of an inelastic time-history dynamic analysis. The r

Abstract:

Performance-based earthquake engineering aims to describe the seismic performance of a structure using metrics that are of immediate use to both engineers and stakeholders. A rigorous yet practical implementation of performance-based earthquake engineering methodology is used to compare the seismic performance of two steel, concentrically braced structural systems, an inverted-V-braced frame and a suspended zipper-braced frame. The principal difference between these two structural systems is the design approach used to transfer the unbalanced forces when the braces buckle. A probabilistic seis

The performance of buckling-restrained brace and the stress mechanism of interior joints in RC frame are both briefly introduced,based on which interior joints strength of buckling-restrained braced frame of reinforced concrete is studied，and contributions to the shear strength of the joint made by brace is therefore summarized. These results can serve as references for the design of interior joints strength of buckling-restrained braced frame of reinforced concrete to meet the “strong connection-weak connected member” requirement.

Because the repairing work of beam and floor after earthquake were great, and the cost were higher, the generalize application of eccentrically braced steel frame were limited. A new braced steel frame system was suggested, which was energy dissipating eccentrically brace. The experimental data of new and conventional D-type eccentrically braced steel frame system were achieved by two specimens under cyclic loading. Results indicated that the new system could put off yielding, reduce earthquake input energy and breakage of the link, reduce repairing load after earthquake, and have preferable d

Abstract:

In seismic design of structures, determination of number and position of braced frames, considering the architectural scheme of projects, is usually confronted by obstacles. Due to this fact, in some cases, selecting the best location and number of braced bays has led to mistakes in determination of their adjacent members (columns) design loads. One of the seismic design requirements of lateral resisting system is to control the columns adjacent to braced bays for load combinations of amplified seismic load, which is a function of over-strength factor of the structure.

Abstract:

Rectangular hollow structural sections (HSS) are commonly used as bracing in concentrically braced frames (CBFs) designed and detailed for seismic design requirements. As the primary yielding component in CBFs, braces are expected to sustain large inelastic axial deformation during earthquake loading. It is well known that their deformation capacity depends on the width-to-thickness ratio (local slenderness). Until 2013, HSS sections were produced to meet ASTM standard A500/A500M; after 2013, the ASTM 1085 specification was implemented, and since that time, HSS sections have also been produced

Repeated dynamic loads on multiple stories structure may cause damage in the midst of natural disaster, such as earthquakes and landslides, hence it is necessary to observe how the response occurs. Therefore, this paper studies the performance of two-story steel frame without braces and with inverted V concentric braces. Both frames were given a static and a dynamic load in the form of a sinusoidal load for 2 seconds in the form of forced harmonic vibration. After the dynamic load is turned off, harmonic free vibration applies. Vibration is given to the weakest orthogonal axis on the frame wit

Steel structures have been playing an important role in the construction industry in recent years. It is necessary to create a model that performs well under seismic loading. Seismic performance of multi-storey steel framed buildings is designed as per the provisions of the Indian Code (IS 800 -2007). The ductility of the structure can be increased by adding steel support to the structure. There are different types of support for retrofitting.
