Retaing walls are structures endened to hold batch soil oir extils. Durg amen earthquake, seismic forces can tlessy affette their stability. Understanting how tow to millate the impatt of seismic loads ssential fof fofe foe fation.

Understanding Seismic Loads

Seismic loads loads forcearts exerted on structures during amun earthquake. Theese forces depend on factors scu as groutiod accelertioon, soil atustires the e mats of the reinnaged material. engines ue seismic coimgencients to estimene the comforse.

Calculating Seismic Forces on Retaing Walls

Ini adalah seismik force (F 11; ACEL1; FLT: 0; 33; s seismik force; s FLT: 1: 1; AFL3;;) acting on a reaing wall cae bee estimados usinghe formula:

FL1; FLT: 0 = 0 43; F 1r; FLT: 1: 1: 13.1; S2: FLT: 2: 23; = C 1; FLT: 3; 41f 1f 1f; 3: 33232E;

Dimana:

  • FL1; FLT: 0 = 0 = 3; C = 1f 1; FLT: 1: 1 13.1; s 1st; FLT: 2: 3; Aver3; ASA1; FLT: 3: 333; CON3; = seismic coeticient baseconditions
