Research on wave forces attacking a vertical structure has been conducted worldwide. Morison’s equation commonly used to describe the phenomenon of the action for offshore structures, while for nearshore structures Goda’s equation is more reliable. Wave impact on vertical breakwaters is dangerous for vertical structures, both for walls and columns. Wave pressure distinguished for wave crest and wave trough, assumed to be distributed as a trapezoidal shape like along the vertical wall. The wave force consists of wave pressure on the front of the vertical wall and buoyancy, and uplift pressure in the vertical direction. In this research, a 2-dimensional physical modelling is carried out to observe the response of a vertical structure due to a wave action. Wave forces are measured using a flexi force sensor for both horizontal and vertical forces. Time series of incident wave and waveforces acting on the structure are recorded simultaneously and it clearly depicts the relation between them. The wave forces at the structure are linear to the height of the action waves. Periodical wave action results in the pushing forces at the structure to be higher than the pulling forces, as extra drift forces appear due to the shallow water wave condition.

波力攻击垂直结构的研究已在世界范围内进行。Morison 方程常用于描述近岸结构的作用现象，而对于近岸结构，Goda 方程更为可靠。波浪对垂直防波堤的冲击​​对于垂直结构来说是危险的，无论是墙壁还是柱子。波浪压力区分为波峰和波谷，假设沿垂直壁呈梯形分布。波浪力由垂直壁前部的波浪压力和浮力以及垂直方向的抬升压力组成。在这项研究中，进行二维物理建模以观察垂直结构因波浪作用而产生的响应。波浪力使用弹性力传感器测量水平和垂直力。同时记录了入射波和作用在结构上的波力的时间序列，清楚地描绘了它们之间的关系。结构上的波浪力与作用波的高度成线性关系。周期性波浪作用导致结构处的推力高于拉力，因为浅水波浪条件会出现额外的漂移力。
