Experimental Determination of Required Lateral Restraint Forces for Z-Purlin Supported, Sloped Metal Roof Systems
… the current provisions for predicting required lateral restraint forces in Z-purlin supported, sloped metal roof systems under gravity loads. A proposed prediction equation, relying heavily on engineering principles, has been developed because the current provisions in the specification are …

Prediction of Lateral Restraint Forces in Sloped Z-section Supported Roof Systems Using the Component Stiffness Method
… members in metal building roof systems. Lateral restraints are required to maintain the stability of a Z-section roof system and provide resistance to the lateral forces generated by the slope of the roof and the effects due to the rotation of the principal axes of the Z-section relative …

Lateral Restraint Brace Forces in Quarter Point and Third Point Plus Support Braced Z-Purlin Supported Roof Systems Subject to Gravity Load
… was to develop design equations that predict lateral restraint forces in two commonly used Z-purlin supported roof systems. These are quarter point bracing and third point plus support bracing. To that end, a stiffness model used in the past has been reintroduced. This model has been modified …

Estimation of Required Restraint Forces in Z-Purlin Supported, Sloped Roofs Under Gravity Loads
… specification provisions for the prediction of lateral restraint forces in Z-purlin supported roof systems under gravity loads are in Section D3.1 of the 1996 AISI Cold-Formed Specification. The design equations contained in these provisions are empirical and based on statistical analysis. They …

Effect of Lateral Stiffness on Bridge Deck Performance
… membrane stress set-up as an effect of the lateral restraint surrounding the deck slab known as Compressive Membrane Action (CMA). It has been proved through research that most design codes underestimate the strength of laterally restrained slabs. However, there is still a lack of acceptance …

Evaluation of post punching capacity of flat plates under progressive collapse
… the effect of two parameters, anchorage and lateral restraint conditions, will be incorporated. The proposed model was found to accurately estimate the post punching capacity of the experimentally tested specimens provided by Peng et. al. 2016. The average ratio of the experimental peak …

Punching failure and compressive membrane action in reinforced concrete slabs
… prediction of the enhanced punching strength of laterally restrained slabs. The procedure is presented as a rigorous method which is suitable for the analysis of slabs for which the degree of lateral restraint can be accurately assessed. Furthermore, a simplified approach which is applicable to …

Modelling the crashworthiness of specialist wheelchair devices
… impact simulations also highlighted the poor lateral restraint ability of the 4-point webbing tie-down system and also the importance of sufficient lateral support on the wheelchair for occupant protection.

The real strength of laterally restrained reinforced concrete slabs
… reason for the strength enhancement exhibited by laterally restrained slab system . This strength enhancement is in excess of that estimated by standard flexural and shear design methods.<br/><br/>Although of the fact that the consideration of CMA in design can lead to substantially reduced …
