Seismic Design - Design Concepts (PDF) CEB Bulletins No. The paper will outline and compare the three methods, and discuss them in the context of Special considerations for suspended ceilings. During the 1995 Kobe earthquake, the Hanshin Expressway Kobe Route was subjected to near-field strong ground motions, resulting in serious damage to a large portion of the Kobe Route. There are several fundamental concepts that the designer can draw on to achieve this goal. Thomas Telford Ltd., London) design have now matured to the stage where seismic assessment of existing structures, or design of new structures can be carried out to ensure that particular deformation-based criteria are met. Seismic design concepts A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles to the structural elements and system that make up the building. Another fundamental concept in engineering – bracing – involves added additional elements to a frame in order to increase its ability to withstand lateral loads. The design base shear is derived from a modified energy balance equation incorporating the concept of seismic force reduction factor and the displacement amplification factor. basic principles guiding the seismic design of structures. In any real-world situation, it is important to seek proper advice from a professional structural engineer before any work is undertaken. The emphasis is placed on delineating the concept of seismic design loads and important aspects of the dynamic behaviour of piles in liquefiable soils. This moment level is labeled as probable flexural strength, Mpr. This module is intended for an engineer unfamiliar with structural dynamic concepts for seismic design. Instructional Material Complementing FEMA 451, Design Examples Design Concepts 7 - 4 Seismic Design Practice in the United States continued • For reasons of economy and affordability, the design forces are much lower than those that would be required if the structure were to remain elastic. Seismic Conceptual Design of Buildings – Basic principles for engineers, architects, building owners, and authorities Hugo Bachmann. uses the Seismic Design Category (SDC) concept to categorize structures according to the seismic risk they could pose. There are two main varieties of braced frames – concentric and eccentric. 236. Correct design concept The correct approach is to select an anchor that is suitable for use under seismic conditions and to design it as per current available literature or standards for given design conditions. Kontakt. The focus of discussion is on design concepts and issues more routinely used or encountered by structural engineers during seismic design of new or retrofitted pile foundation systems representative of those used for bridges and buildings. Some new concepts of seismic design were adopted in this code by drawing on the lessons of the 1995 Kobe earthquake that caused devastating damages. Module Format 5 GENERAL CONCEPTS OF EARTHQUAKE RESISTANT DESIGN bedded or tied into the main struc-ture of the building.

(Reference is made to (31).) There are several fundamental concepts that the designer can draw on to achieve this goal. By using our services, you agree to our use of cookies. Designing a building is a complex and specialist undertaking that is well beyond the scope of this guidance, but a few of the basic concepts are briefly introduced here. It has been successfully applied in seismic analyses of buried pipelines under fault crossing and unburied pipelines with a subsea manifold by using a static analysis and a dynamic time history analysis. Seismic Design in Steel -- Concepts and Examples (Part 1): Introduction to Effective Seismic Design (R1) This 8-part course is intended to provide engineers with guidance on applying the AISC seismic design requirements, correctly and efficiently, on typical projects in regions of moderate or high seismicity. 1.5 Force-based Design to Displacement-based Design 13 2 Earthquake Demand on Buildings 2.1 Seismic Design Force 15 2.2 Dynamic Characteristics of Buildings 18 2.2.1 Natural Period 18 (a) Fundamental Natural Period of Building 19 (b) Factors influencing Natural Period 20 (1) Effect of Stiffness 21 (2) Effect of Mass 22 14.3 Conclusions. Real buildings usually integrate several different techniques at the same time to limit seismic forces, and a typical medium or high-rise reinforced concrete structure, for example, may use several of these concepts at the same time. Seismic Design Concept 1 Ductility Design • A Reduced Design Seismic Force Can Be Used IF Sufficient Ductility Is Built into the Structure • But Only a Certain Elements Are Strategically Designated to Serve as Structural Fuses, i.e., Deformation-Controlled Elements (DCE) Seismic Design of Foundation: Concepts and Applications justifies its title by delivering a solid exposition of theory along with practical worked out examples that are required for designing the foundations of different structures like buildings and bridges subjected to seismic loading. A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles. Seismic load path and dynamic behaviour of multi-storey structure; Please note this module is not aimed to comprehensively teach ALL concepts related to dynamic concepts for Seismic Design. A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles to the structural elements and system that make up the building. Bolt and nut connection design; Tension member design; Geotechnical Engineering; Earthquake Analysis. Basic concepts for seismic design codes are outlined with special emphasis on the role of ductility.

Keywords INTRODUCTION The intent of this paper, is to focus on design concepts EARTHQUAKE-RESISTANT DESIGN CONCEPTS 4.2 Nonbuilding Structures The NEHRP Recommended Seismic Provisions also includes seismic design crite-ria for many structures that are not considered to be buildings. This resource page provides an introduction to the concepts and principles of seismic design, including strategies for designing earthquake-resistant buildings to ensure the health, safety, and security of building occupants and assets.The essence of successful seismic design is three-fold. •Seismic requirements safeguard against major failures and loss of life– they DO NOT necessarily limit damage, maintain function, or provide for easy repair.
