A series of static tests on thin walled square box specimens, direction fixed at their ends, and subjected to axial overload until gross inelastic distortion occurred are described in this paper. Observations were made on the mode of buckling, the peak load sustained, and the load-shortening characteristics. A simple theory is also presented in which no account is taken of elastic deformations, but folding is assumed to occur along straight lines, together with kinking of the corner edges, and, by assuming a kinematically admissible pattern of such folds, a virtual work analysis is derived to predict theoretical load-shortening characteristics. Reasonable agreement is shown to exist between the theoretical and experimental results. B. Rawlings and P. Shapland

Damped Earthquake Response of Non-symmetric Multi-storey Structures

Damped Earthquake Response of Non-symmetric Multi-storey Structures

The analysis of the damped and undamped earthquake response of non-symmetric multi-storey structures is presented, with consideration of the foundation mass and partial restraint of the structure in the subgrade. The analysis is based on the continuous connection method using the normal modes of the structure. Proportional and constant damping are considered. E. Mendelson and M. Baruch

Correspondence on Yield Line Analysis of Reinforced Concrete Skew Slabs under Highway Bridge Loading

Correspondence on Yield Line Analysis of Reinforced Concrete Skew Slabs under Highway Bridge Loading

In the section of the paper headed 'Serviceability limit-state' the authors state that further attention should be given to the problem of cracking in skew slabs where the cracks do not necessarily form perpendicular to the reinforcement. In fact, work has been carried out athe Cement and Concrete Association on this problem with particular reference to slab bridges. L.A. Clark

The Design of Reinforced Concrete Deep Beams in Current Practice

The Design of Reinforced Concrete Deep Beams in Current Practice

The design of remforced concrete deep beams is not yet covered by the new British Code CP110:1972. The major design methods currently available are reviewed in this paper, namely, those proposed by ( l ) the European Concrete Committee in 1970; ( 2 ) the American Concrete Institute in 1971; and (3) the Portland Cement Association in its long standing document ST66 issued in 1946. The more recent proposals by the authors and their co-workers are also explained; unlike the others, the authors' proposals cover also deep beams with web openings. F.K. Kong, P.J. Robins and G.R.
