“…For the same magnitude of lateral load of 450 kN, group interaction obtained showed an increase in lateral pile displacement. This conclusion was also supported by Brown et al [5], and Rollins et al [20][21][22][23][24][25][26][27][28][29]. It can be seen that the pile spacing less than 6D resulted in a large lateral deflection of a pile group under applied load due to group high group interaction effect.…”

“…The methods of operation of these systems can be broadly categorised as mechanical (Rao et al, 1998), electromechanical (Basack, 2005;LeBlanc, 2009;LeBlanc et al, 2010), pneumatic and (or) hydraulic (Chandrasekaran et al, 2010;El Nagger and Wei, 1999;Kumar and Rao, 2012). As discussed and presented in these experimental studies, the loading systems have varying complexities in their operation and capabilities to simulate the field conditions.…”

“…As discussed and presented in these experimental studies, the loading systems have varying complexities in their operation and capabilities to simulate the field conditions. For instance, some loading systems (Rao et al, 1998;El Nagger and Wei, 1999) can apply only monotonic lateral loading in a certain range. Others can apply one-way repeating load and have been used in studies to apply limited numbers of lateral loading cycles (Chandrasekaran et al, 2010;Kumar and Rao, 2012;Qin, 2010).…”

“…Reese et al (1974) and Ramakrishna and Rao (1999)) and to investigate the influence of the piles' cross-section and rigidity on lateral load-carrying capacity (Mahmoud and Burley, 1994;Rao et al, 1998;Raongjant and Meng, 2011). Some of these studies have focused on investigating the behaviour of tapered piles (Dü hrkop et al, 2010;El Nagger and Wei, 1999), finned piles (Peng et al, 2011) and (or) piles subjected to many thousands of load cycles in the lateral direction (Dü hrkop et al, 2010;LeBlanc et al, 2010;Peng et al, 2011;Cuéllar et al, 2012).…”

2This paper deals with an important problem of the effect of repeating lateral loads on large-diameter monopile foundations for offshore wind turbine (OWT) structures. The cycles of typically low-amplitude repeating lateral loads and moments generated by various environmental factors are resisted by horizontal earth pressures mobilised in the soil surrounding the pile. Laboratory testing on reduced-scale piles is an efficient and economical way to investigate such pile-soil behaviour. This paper presents the development of a new mechanical loading system to apply many thousands of repeating cycles of lateral load in different forms to a 1g model, with full control provided over the loading direction (i.e. one-way or two-way lateral loading), amplitude, frequency and waveform shape (e.g. sinusoidal, square or haversine). Compared with equivalent setups employing pneumatic or hydraulic actuators, the new loading system is able to produce similar performance at lower cost and also provides more control over the waveform shape. A programme of lateral load tests, each involving many thousands of load cycles, was performed on a rigid model pile installed in dry sand beds to demonstrate some of the main capabilities of the new system.

“…Two modes of failure yielding of the soil along the length of the pile (short-pile failure), and yielding of the pile itself at the point of maximum moment (long-pile failure) are consider. Narashimha Rao et al (1998) investigated the lateral load capacity of pile groups in soft marine clay and they found that the lateral load capacity mainly depends on rigidity of pile soil system. Many analytical approaches have been developed in recent years for the response analysis of laterally loaded piles.…”
