This can be determined from elasto-plastic response graphs. One example is Figure of UFC The maximum displacement is a function of the ratio of applied load to yield load and duration of loading to natural period.

    Deformation-Controlled Design of Reinforced Concrete Flexural Members Subjected to Blast Loadings Hai-Cheng Rong1 and Bing Li2 Abstract: Both maximum displacement and displacement ductility factors should be considered in the design of a blast-resistant structure since both parameters correlate with an expected performance level of a reinforced concrete RC structural member during a blast event.

Vol. 62, No.September-October Published by: Society of American Military Engineers. Design of Flexural Members for Static and Blast Loading (ACI Monograph No. 5) by J. Allgood, G. Swihart. Design of Flexural Members for Static and Blast Loading. In this article the attention is drawn towards the design of flexural members subjected to axial force.

It is shown that while using the charts of SP the design not only becomes uneconomical but also unconservative. There are cases when a flexural member is. Structural Design II My = the maximum moment that brings the beam to the point of yielding For plastic analysis, the bending stress everywhere in the section is Fy, the plastic moment is a F Z A M F p y ⎟ = y 2 Mp = plastic moment A = total cross-sectional area a = distance between the resultant tension and compression forces on the cross-section a A.

for blast load due to the reason that the magnitude of load caused by blast is huge and, the cost of design and construction is very high.

As a result, the structure is susceptible to damage from blast load. Recent past blast incidents in the country trigger the minds of developers,Author: Umesh Jamakhandi, S. Vanakudre. Blast wave Figure 3: Blast loads on a building If the exterior building walls are capable of resisting the blast load, the shock front penetrates through window and door openings, subjecting the floors, ceilings, walls, contents, and people to sudden pressures and fragments from shattered windows, doors, etc.

Building components notCited by: apply blast force as an impulse load because blast force does not prevail for longer period of and it last’s for a few milli-seconds, so time -history method is most suitable for designing a building for blast loads and the method used for preliminary design is static analysis by imposing dead, live loads and combination loads Figure 1.

• Blast loading is a short duration load also called impulsive loading. • Mathematically blast loading is treated as triangular loading.

• The ductility and natural period of vibration of a structure governs its response to an explosion. Drag exerted by the blast winds required to form the blast wave [11]. These winds push, tumble and tear objects. Blast pressure can create loads on buildings that are many times greater than normal design loads (Fig 3), and blast winds can be much more severe than hurricanes.

Live load (L). Snow load (S). Earthquake (E) load is determined according to the provisions of "Iranian Code of Practice for Seismic Resistant Design of Buildings" known as standard No The building is located in a seismic region and wind load is assumed not to control the design.

This will equal the number of cubic yards that can be broken at 1 lb/cy. Determine approximate square pattern from Table 1 of Blaster’s Guide, or multiply the number ob. Calculation of blast loads 1. By hi 2.

The use of explosives by terrorist groups around the world that target civilian buildings and other structures is becoming a growing problem in modern societies. The problem of structural resistance under explosive loads has been under investigation for many years and has been well advanced in the military community.

This is also the. Various studies were also conducted on the effect of blast loading on bridge columns. Williamson et al. studied the response of reinforced concrete bridge column subjected to blast load. They identified the design parameters influencing the performance of reinforced concrete : Anusree A, Ann M Biju, Athulya Sreesa E K, Devika Ramesh, Rinsa K.

RE: How to trasform blast load to static load ketchi (Structural) 29 Mar 10 I think It's better to try and do a full dynamic analysis. there is an aproximation used to convert the multi-degrees of fredom system into a single-degree of freedom system, But by assuming a "static load" i think you'll pretty much miss the real behavior of.

In the current technical guide, an overview of a design procedure for structures under blast loading is provided. The material presented has been collected from various sources and.United l Housing Administration 1 + More More.Static load is the load which does not change in magnitude or direction and gradually increases to a steady value e.g.

dead weight of machine elements. Dynamic load is the load which changes in magnitude or direction or both with respect to time e.g. load acting on the connecting rod of an internal combustion engine.
