Abstract: This article presents the results of an experimental investigation of the behavior of circular reinforced concrete columns strengthened with fiber reinforced polymer (FRP) sheets under the combined action of axial loads and bending moments. Test parameters included the absence/presence of FRP jackets, fiber orientation and stiffness of the jacket. Test results proved that the investigated FRP strengthening schemes can be efficiently used to enhance the load-carrying capacity and deformability of eccentrically loadedcolumns. When compared to the FRP hoop confined columns, the inclusion of an axial FRP sheet was found to have negligible effects on the axial column resistance however, the longitudinal fibers increased both the axial and flexural rigidities of the strengthened columns. Using an axial FRP sheet confined by two hoop FRP sheets enhanced the columns' rotational capacities allowing them to absorb eccentric loads with increasing lateral deflections.

Abstract: Temporary works designers influence construction ergonomics directly and indirectly. The direct influence is because of design, details, and method of connecting, and depending upon the type of procurement system, supervisory, and administrative interventions. The indirect influence is because of the type of procurement system used, prequalification, project duration, partnering, and the facilitating of pre-planning. A questionnaire survey was administered among attendees attending an inhouse support work designer and supplier ‘designing for construction ergonomics’ workshop. The following constitute the salient findings. Quality, is more important to the respondents’ organisation than construction ergonomics, and project health and safety (H&S). A range of temporary works design related aspects impact on construction ergonomics, and the respondents’ organisation considers / refers to such aspects frequently, and on a range of design, procurement, and construction occasions.
